General remarks

There are not any accurate doses or founded consistent dosing schedules for items such as for instance fresh marijuana, smoked/vapourized cannabis, or cannabis oil.

Dosing remains highly individualized and relies to an extent that is great titration (in other words. locating the dose that is right possible healing results are maximized while undesirable or harmful impacts are minimized). Probably the most approach that is prudent dosing within the lack of evidence-based recommendations is always to “start low and go sluggish.”

Nevertheless, greater doses of THC (and CBD) are connected with an elevated danger of experiencing adverse or effects that are harmful.

Clients without any previous knowledge about cannabis and initiating such treatment the very first time are cautioned to start at a rather low dose ( ag e.g. 1 mg THC) and also to straight away stop therapy if unsatisfactory or unwanted unwanted effects happen ( e.g. disorientation, dizziness, and lack of coordination, agitation, anxiety, quick heartbeat, upper body discomfort, low bloodstream pressure/ feeling faint, depression, hallucinations, or psychosis).
