Everything You Need to Know About THC

If you’ve ever explored the world of cannabis, you’ve likely heard the term THC — short for tetrahydrocannabinol. It’s the compound that makes cannabis famous for its psychoactive effects, but there’s far more to it than just “getting high.” Whether you’re a first-time consumer or a seasoned cannabis enthusiast, understanding THC is essential for making informed decisions about what you consume and how it affects your body and mind.
In this comprehensive guide, we’ll break down what THC is, how it works, its effects, potential benefits, differences between THC vs CBD, and even touch on products like THC oil, THC diamonds, THC pens, and THC syrup. We’ll also cover important topics like THC withdrawal and safe consumption practices — all through the lens of cannabis delivery in the Greater Toronto Area.
What Is THC?
THC, or tetrahydrocannabinol, is the main psychoactive compound found in the cannabis plant. It’s responsible for producing the euphoric, relaxed, and sometimes creative sensations people associate with being “high.”
When you consume THC — whether through smoking, vaping, or edibles — it interacts with your body’s endocannabinoid system (ECS). Specifically, it binds to CB1 receptors in the brain and nervous system, influencing mood, appetite, pain perception, and memory.
The strength and type of high you experience depend on multiple factors:
- The strain of cannabis
- The THC percentage
- The consumption method (e.g., inhaling vs ingesting)
- Your tolerance and body chemistry
At Highest Farmacy, we source only lab-tested cannabis products to ensure quality, consistency, and safety for our customers across the GTA.
THC vs CBD: What’s the Difference?
A common question among cannabis consumers is: What’s the difference between THC and CBD?
While both are cannabinoids — naturally occurring compounds in the cannabis plant — they have very different effects:
| Feature | THC | CBD |
| Psychoactive Effects | Yes – produces a high | No – non-intoxicating |
| Receptor Interaction | Primarily CB1 receptors | Primarily CB2 receptors |
| Common Uses | Euphoria, relaxation, pain relief | Anxiety relief, inflammation, seizures |
| Legality (Canada) | Legal for adult use | Legal and widely available |
So when it comes to THC vs CBD, it’s really about the experience you’re seeking.
- THC is ideal for users looking to relax, enhance creativity, or experience euphoria.
- CBD, on the other hand, provides calming effects without the high — making it suitable for wellness and medicinal use.
Many cannabis products now combine both cannabinoids for a balanced, synergistic effect, known as the entourage effect.

THC Effects: What Happens When You Consume It?
The effects of THC can vary depending on the dose, strain, and delivery method, but here’s what most users can expect:
Short-Term Effects:
- Euphoria and relaxation
- Heightened senses (taste, sound, colour)
- Increased appetite (“the munchies”)
- Altered perception of time
- Laughter and sociability
Potential Side Effects (in high doses):
- Dry mouth and eyes
- Short-term memory issues
- Increased heart rate
- Anxiety or paranoia (in sensitive users)
Long-Term Effects:
Regular use may lead to tolerance, meaning you’ll need more THC to feel the same effects. However, when used responsibly, many people enjoy THC for its ability to ease pain, improve sleep, reduce stress, and enhance creativity.
If you’re new to cannabis, start low and go slow. At Highest Farmacy, we offer detailed product descriptions and THC percentages to help you find your ideal match safely.
Types of THC Products
Cannabis has come a long way from traditional joints. Today, there are multiple innovative ways to enjoy THC — each offering unique experiences. Let’s explore some of the most popular THC products available for weed delivery in Toronto and the GTA.
1. THC Oil
THC oil is a concentrated cannabis extract that can be taken sublingually (under the tongue), added to food, or vaporized. It offers:
- Precise dosing
- Discreet consumption
- Long-lasting effects
It’s perfect for medical users or anyone who prefers not to smoke. At Highest Farmacy, you’ll find premium THC oils from trusted Canadian producers, with a range of potencies to fit your needs.
2. THC Diamonds
THC diamonds are one of the most potent cannabis concentrates available — named for their crystalline appearance. These are made by extracting and crystallizing THCA, which converts into THC when heated.
With purity levels often exceeding 95% THC, these are for experienced users only. They deliver intense effects, perfect for dabbing or mixing with other concentrates for a next-level experience.
Highest Farmacy offers top-tier THC diamonds sourced from reputable Canadian labs, ensuring purity, potency, and exceptional flavour profiles.
3. THC Pens
THC pens (also known as vape pens) are sleek, portable, and easy to use — making them a top choice for on-the-go cannabis enthusiasts. Each pen contains a THC oil cartridge that delivers smooth, controlled doses with every puff.
Benefits include:
- Discreet and odourless use
- Quick onset of effects
- Rechargeable or disposable options
They’re ideal for anyone in the GTA looking for convenience without compromising on quality. Browse our THC vape pens for premium brands and flavours.
4. THC Syrup
THC syrup is a sweet, drinkable cannabis product infused with THC oil or distillate. It can be mixed with beverages or taken directly by the spoonful.
Why people love it:
- Fast-acting effects (faster than edibles)
- Precise dosage control
- Delicious flavours
You’ll find THC syrups available in a variety of potencies — from mild microdose blends to strong formulations for experienced users. Always read the label carefully before consuming.
The Science Behind THC
To understand how THC works, it helps to look at your endocannabinoid system (ECS) — a network of receptors found throughout your brain, organs, and immune system.
The ECS helps maintain homeostasis — or balance — in your body. When THC enters your system, it mimics naturally occurring compounds called endocannabinoids, binding to CB1 receptors in your brain and CB2 receptors in your body.
This interaction is what produces the wide range of THC effects — from pain relief to euphoria. Scientists are still studying the full scope of THC’s potential, but it’s already being explored for therapeutic benefits in:
- Chronic pain
- Appetite stimulation
- Nausea control (especially in chemotherapy patients)
- Insomnia
- PTSD and anxiety relief
THC Withdrawal: What You Should Know
While THC is not considered physically addictive, heavy long-term use can lead to mild THC withdrawal symptoms when stopping suddenly. These can include:
- Irritability or mood swings
- Sleep disturbances
- Decreased appetite
- Restlessness
The good news? These symptoms are temporary and typically fade within one to two weeks. Staying hydrated, exercising, and maintaining a healthy diet can help ease the transition.
If you plan to take a tolerance break, remember: moderation and mindfulness go a long way in maintaining a balanced relationship with cannabis.

How Long Does THC Stay in Your System?
The duration THC stays in your system depends on several factors:
- Frequency of use
- Body fat percentage
- Metabolism speed
- Consumption method
For occasional users, THC may stay in your system for 1–3 days, while daily users may retain traces for up to 30 days or longer. This is due to THC’s fat-soluble nature — it binds to fat cells and metabolizes gradually.
The Legal Status of THC in Canada
Since October 17, 2018, THC has been fully legal for adult use across Canada under the Cannabis Act. This means adults aged 19+ (in Ontario) can legally buy, possess, and consume cannabis products, including THC oil, THC pens, and THC edibles.
However, there are still important rules to follow:
- You can possess up to 30 grams of dried cannabis (or equivalent).
- Consumption is allowed in private residences and certain outdoor spaces.
- Driving under the influence of THC remains strictly prohibited.
At Highest Farmacy, we comply with all provincial and federal regulations to ensure safe, legal, and discreet cannabis delivery across the Greater Toronto Area.
The Benefits of THC
When used responsibly, THC offers numerous potential benefits — both recreational and medicinal.
Medical Benefits
- Pain relief (chronic, neuropathic, and inflammatory)
- Appetite stimulation for medical conditions
- Nausea reduction (especially in chemotherapy)
- Sleep aid for insomnia sufferers
- Mood enhancement for depression and anxiety
Recreational Benefits
- Euphoria and relaxation after a long day
- Increased creativity and introspection
- Enhanced sensory experiences (music, art, and food)
- Social connection and mindfulness
Cannabis is more than just a product — it’s a way to unwind, connect, and explore. That’s why Highest Farmacy is proud to provide high-quality THC products that cater to every type of user, from the curious beginner to the experienced connoisseur.
Choosing the Right THC Product for You
With so many THC products on the market, it’s important to choose what fits your lifestyle and goals. Here’s a quick guide:
| Goal | Recommended Product | Why It Works |
| Relaxation and sleep | THC oil or edibles | Long-lasting, calming effects |
| Creativity or daytime focus | THC vape pen | Controlled, quick hits |
| Social experience | THC flower | Classic, shareable experience |
| Strong effects | THC diamonds | Extremely potent and pure |
| Discreet dosing | THC syrup or microdose gummies | Portable, subtle, easy to measure |
If you’re unsure where to start, Highest Farmacy’s cannabis experts can guide you through strain selection, potency, and product type to match your needs.
CBD vs THC: The Perfect Partnership
It’s not a matter of THC vs CBD, but rather THC and CBD working together. This synergy — called the entourage effect — enhances the therapeutic potential of both cannabinoids.
For instance:
- CBD can reduce the anxiety that sometimes accompanies high doses of THC.
- THC enhances the mood-boosting effects of CBD.
This balance allows users to enjoy the benefits of cannabis without the intensity of a full THC high. Many modern products are formulated to deliver this harmony — such as 1:1 THC-CBD oils, edibles, and vape pens.
Responsible THC Consumption
To enjoy the best experience, follow these golden rules:
- Start low, go slow. Especially with weed edibles and cannabis concentrates.
- Know your tolerance. Take breaks when needed.
- Stay hydrated. THC can cause dry mouth.
- Avoid mixing with alcohol or other substances.
- Store safely — keep cannabis away from pets and children.

Different Types of Vape Products
Different Types of Vape Products

There are different vapes and vape products to suit everyone’s preferences. The diversity of these products makes it possible for you to enjoy the vaping experience.
The different types of vapes include disposables, e-cigs, vape pens, pod mods, mods, and so much more.
What is a Weed Vape?
A vape is an electronic cigarette. This device heats the liquid or substance inside the device to create a specific vapour you inhale to get the high feel most people go for. There are different types of vapes.
With this in mind, a weed vape is used to vape in different forms. Vaping is meant to help the product get into the bloodstream directly without going through other channels. It feels like a warm little cloud entering your mouth.
The feeling you get depends on the intensity of the e-juice and the product’s flavour. The weed you vape may come in different flavours as well. Choose flavours that best suit you or those you prefer to enjoy more.

What are the Components of a THC Vape?
As already mentioned, a vape is a device used to consume specific vaping products, either nicotine based from tobacco or cannabinoid-based from weed. A THC vape will contain THC as the primary cannabinoid that users vape whenever they use the vape.
A THC vape, therefore, consists of a heating element known as the atomizer, a power source which is the vape battery, a wick, and a tank cartridge or container, which holds the vaping e-juice/ liquid. The atomizer often contains nicotine, but in this case, cannabis vape contains a mixture of terpenes, cannabinoids, and thinning agents used as solvents and additives.
To be even more specific, THC cartridges have the THC cannabinoid as the primary type of cannabinoid in the atomizer. The flavours come in diverse offers making it easy for users to choose what they love—these range from sweet flavours or sour and original flavours like tobacco.
A vape cartridge makes it easy for users to access their cannabinoids without smoking. In addition, these THC vapes are more convenient and easy to handle, even for beginners, as no mastery of rolling joints is required.
Different Types of Cannabis Vape Products
You will be surprised to know that numerous vape products are available today. With more people embracing cannabis and governments even legalizing some of the products for recreation and medicinal use, it is not surprising that cannabis vape products are flooding the market.
It is common to find people filling their weed carts with some of these vape products.
The different vapes you will find in weed dispensaries, and online vendors include:
- Weed pens – These devices allow users to vaporize THC or CBD oils. There are different weed pen types available in all sizes and shapes.
- THC vape pen – A THC pen refers to the THC vaping device, sometimes known as the wax pen, dab pen, or vape pen. Some people refer to it as a mod or e-hookah.
- Disposable vapes – Disposable vapes offer all-in-one vapes, including pre-filled pods with an integrated coil and a battery. A disposable vape pen is not rechargeable.
- Vape cartridge– weed cartridges have concentrated fillings that can maintain flavour and potency much longer than flowers.
- Weed vape pen – A weed pen is a device held by hand. This device comes with a battery linked to a cannabis concentrate cartridge. The vape cartridge is filled with the substance you vape when using the device.
- Vape pens – A vape pen will vaporize but not burn the cannabis you want to ingest. Therefore, you end up with vapour and not smoke
- Dab pens/ wax pen – A dab pen or wax pen is simply a concentrate vaporizer that heats the extracts until they vaporize. The pen comprises a heating element/ atomizer, mouthpiece, and battery.
- Shatter pens/ vape pens – A shatter pen is a device that helps with THC inhalation. It is more hygienic and easy to handle compared to traditional forms. It is commonly known as a vape pen and is convenient and odourless to use and carry around.
- Live resin pens utilize fresh but frozen cannabis to release an intense terpene flavour profile. In addition, they deliver a full-spectrum cannabinoid experience, especially with reflective strains such as indica, hybrids, and Sativa. This explains why we have specific live resin pens, such as the Sativa THC pen.
Note that some of the products mentioned above can be used interchangeably. However, sometimes the different kinds of vapes in the market differ very slightly for them to make a significant difference. Therefore, the most important thing is to find a device that delivers the best weed vape experience.

What Marijuana Vape Product is For Me?
The type of weed vapes or vaping products you settle for is based on personal preference. What works for one may not necessarily be suited for another. The right products, therefore, are those that you find easy to use, give you the expected result you are going for, and those you prefer.
This means that you should always be open-minded and ready to try as many products as possible before concluding what works. Also, read reviews and choose based on the probability of your likes, not settling for a product blindly.
The most common products you will likely come across are vape pens, mods, e-cigs, and pod mods. Understand how each works before spending your hard-earned cash on any of them.
Where to Buy Weed Vapes Online in Canada?
There are numerous weed vapes online for Canadian customers. Knowing where to get the best products matters as it may influence the quality and functionality of the product. Never ignore the vendor’s reputation when searching.
