Tinctures are often snake oil......and you can't judge it by inspection like you can w/ bud of course.

The best I've had is Sugar Leaf Premium Tincture, the 2X(double strength). Glycerin based, purified by four filterings.

Don't mix tincture. Apply directly under your tongue w/ a dropper. The effect is much different than edibles, closer to smoking but quite a smoother buzz. Fairly quick reacting within 15 minutes.

I've experimented with tincuture w/ no other smoking or any other medical application to obtain pure results. With the Sugar Leaf product, a small 1/2 oz bottle can last me a week (I am a low to mid medicator). You can pack this in your toiletry bag & fly with it (just remove the label to be safe). There are situations/environments where it is so hard to smoke & tincuture works well for that.

If you overindulge, you get sleepy but also a quick, very low-level psychedelic passage - which is quite cool. Then your dreams are unreal & crystal clear. This last part shocked me because regular to heavy smokers have always told me they dream less when medicated than when not medicated.

I can't even picture smoking the equivalent dose I did w/ that tincture experience but if I did, I would be out and probably not remember any part of a dream. Would be interested in other's experience w/ different tinctures sans bud or w/ bud.
