THC Dosage: How Much THC Should You Actually Take?

A standard unit of THC is 5 mg, and most experts suggest beginners start with half of that, 2.5 mg. That standard helps researchers design and interpret studies more precisely. When everyone measures the same way, it's easier to draw conclusions and compare findings across studies. However, there are currently no guidelines on how many THC units make up a standard dose.

Cannabis brands and some organizations offer their own recommendations on how much THC to take. Experts recommend starting with 2.5 mg of THC, half the research standard. They suggest not going over 40 mg of THC per day.

Keep in mind that THC concentrations can vary a lot between products and depending on how you consume cannabis. Even though products list their THC content on the label, there's no guarantee it's accurate. In fact, plenty of products list less THC than they actually contain.

How much THC is safe to take?

There are no official recommendations for a safe amount of THC. That's partly because more research is needed to pin down what a safe dose looks like. On top of that, cannabis affects people differently depending on the type of product, how much you take, how you take it, your tolerance, and your weight, height and age. It's also worth knowing that the endocannabinoid system is different in every person, so we don't all process cannabinoids the same way. That makes it hard for professionals to tell us exactly how much THC is safe.

There are also several different ways to consume cannabis products:

Smoking and vaping:

Dried flower can be smoked in joints or a pipe, or heated in a vaporizer. Cannabis oil can be vaped too.

Eating or drinking:

Cannabis is commonly cooked into food or candy, known as edibles. Cannabis-infused drinks like tea are also common and easy to make.

Concentrates:

Cannabis concentrates, like oils and wax, are made by stripping the resin from the plant using carbon dioxide, alcohol, butane and other methods. Pulling the THC out of the plant this way produces extremely potent concentrates.

How much THC is in cannabis depends on the type of product:

Smokable cannabis covers a wide range of THC content. Some hemp-derived pre-rolls have as little as 0.1% THC, while most dispensary pre-rolls land between 20% and 30% THC by weight.

Where cannabis edibles like gummies or cookies are legal, they usually come in a fixed, regulated dose per serving, commonly 5 or 10 mg of THC. Cannabis concentrates like rosin, dabs, shatter and wax pack the strongest punch, with THC ranging from 54% to 80%.

Because THC affects everyone differently, keeping a journal of your doses and how they felt can help you track your own response. That said, as we always say, the best move is to check with a professional. If you're using THC for medical or therapeutic reasons, talk to your cannabis doctor. And if you're exploring recreationally, talk to a grower friend or a cannabis community. They'll be glad to share their experience so you know where to start.
