Dosage Guidelines

How Much Should I Take? Dosing Your Cannabis.

 

The first thing to know: you can’t overdose on cannabis. But, if you take too much of a THC-rich strain cannabis (which has psychoactive effects) it can get very… let’s just say uncomfortable. You can become sleepy or act irrationally. Finding the right dose of marijuana can be challenging. As described in our Ways to Consume section, there are different methods of consuming cannabis. Each has its own recommended dosage. The frequency of use depends on the method and the symptoms. In some cases, lower dosage causes one effect, while a higher dose can result in the opposite.

 

The bottom line is that it’s still early days of the medicinal marijuana movement, so standard dosage is not yet an exact science. To get you started, here are some baseline dosage recommendations to give you an idea of a general range for each method. You should always ask your medical practitioner to make sure you are taking the right dose for you. If you need a doctor who is experienced with medical cannabis, find a doctor near you using our doctor locator.

Onset of Effects: Slow (1-2 hours)

Duration of Effects: 4-6 hours

Dosage: Edible: 5-10 mgs two times per day (to start – for new users) * **

*Potency depends on the specific item. Estimates for edibles can vary by a factor of 10, due to potency and the recipe used. Capsules often can provide more standardized dosing.

** Some people with a tolerance may use up to 100 mg/dose.

 

Sublingual (tincture/spray) – medicinal compounds absorbed through mucosal surfaces (usually under the tongue) into the bloodstream.

Recommended Dose for This Method: High

Onset of Effects: Moderate (15-30 minutes)

** Spray 2-4 times into the mouth, or use a few drops up to a dropperful, and wait a few seconds before swallowing (Drops can be mixed into a small amount of water or juice to improve the taste).
