depending on the weed really, i dunno what i have at mo, but i get arroused so i pester my gf. does same effect for her so i get lucky.
other's have chilled me from a stressful situation or cleared my head and i have programed a ton, and not had many issues.
another side effect of this one is, it puts me to sleep.
but other than the above, Counter-Strike, and reading... o and fixing up a lil my closet grow room, its an airing cupboard not best, but i am planning for it to be temp, cause i'm gonna move my weight bench (never weightlift after smoking weed, i noticed that i got extremely high whilst lifting the weights dunno why)
and move spare tv etc, partition the room. and build a trench of plants. etc, saw it on a video well kinda they did a whole room, i think it was hightimes or somthing vids i found on net.
