i find that my tolerance and appetite for smoking weed goes up hugely when on shrooms.
if i smoked 7 spliffs in a couple of hours, it would be gooood night normally, but i not only want to smoke that much, but i also manage to when im tripping.
so if your doing it in dam, i suggest getting all your weed in before. most people tend to do it in the hotel first time aswell, being abroad wandering the streets can be very disorientating. we ran out of weed once mid trip, and had to find a coffeeshop and then get some weed, which was so difficult (hilarious in retrospect, but horrid at the time). my sister who was at the counter forgot the word 'weed' and was asking for green hash, and then couldnt understand the types of money in her hand.... the budtender must have ha a long day, as he wasnt impressed
and oh my word is rolling up hard/funny when your tripping.
i actually dont think ive ever done shrooms without smoking, so i cant really comment on that side.....
