I would suggest sticking to milder sativas, that give you more of an elated/happy/energetic high. If you find the effects to be too strong, smoke organic outdoor strains because the THC content is lower and your high could possibly be affected by hydro-grown product that hasn't been flushed properly and has fertilizer and such in it still. At least when you get organic out, you know it's straight up cannabis and you aren't going to get blasted off into space with a few tokes.
