How to use Medical Marijuana

Start Low and Go Slow

The basic principal for dosing medical marijuana is to start with a low dose and to go slow in taking more until the effect of the first dose is fully realized, because the effects of cannabis are not always immediately felt. Starting low and going slow allows patients to accommodate for the different experiences they may have.

Cannabis has a wide margin of safety and there is limited risk of overdose. However, caution is warranted until a patient fully understands the effect that the cannabis may have. Dosage varies greatly among patients, even when treating the same condition.
There are many factors that impact the effect, including:

Amount used (dosage)
Strain used and method of consumption
Experience and history of cannabis use
Mindset or mood
Nutrition or diet


All allowable forms of medical marijuana, including methods of consumption and strain, variety, and strength, are determined by the Commissioner and must be approved by the Commissioner before they can be sold. Smoking as a method of consumption of the only form not left to the Commissioner and specifically excluded from ‘certified medical use’ in the statute.

Inhalation Methods:

Battery-powered handheld vaporizer, Disposable handheld vaporizer with replacement cartridge options, Electric vaporizing device, Metered-dose inhalers (MDI)

Patients should be aware that cannabis use causes short-term impairments in the following brain functions:

Memory, Sense of time, Sensory perception, Attention span, Problem solving, Verbal fluency, Reaction time, Psychomotor control

Cannabis users may “pull themselves together” to concentrate on simple tasks for brief periods of time. That said, performance impairments may be observed for at least one to two hours following cannabis use, and residual effects have been reported up to 24 hours depending on potency of the cannabis, the method of administration, and the tolerance of the user.
Long-Term Cognitive Effects

Consult the advice of your physician if you are a long-term user of medical cannabis and intend to stop using it, or if you are concerned about dependence on or addiction to cannabis. Your physician can help you manage any withdrawal effects that you may experience. Always seek the advice of your physician or other qualified healthcare provider before starting any new treatment or discontinuing an existing treatment with medical cannabis.
