My guess is you do not indulge in cannabis for pain treatment. If you have been on break with cannabis for a long time and are coming back, you will probably need to work your tolerance up.

If you havent been smoking/eating cannabis for like, 2-3 weeks, atleast once a day a two, you cant really judge the cannabis now a day as indica or sativa, in my opinion..

Either one will kick your ass if your tolerance is low. You need to try and get your tolerance up and the high will be WAY more comfortable, predictable, and managable and you will be able to feel and understand the sativa or indica properties you are looking for.

If you cannot indulge for a week or so, you might have troubles getting used to the cannabis because your tolerance is so low.
