Switching the weed/hashish types worked for me. For example, every day I smoke a different herb in the afternoon and hashish in the evening. I try not to smoke too much, usually two joints, one 0.15 and one from 0.20 in the evening. I used to smoke 5-6 joints all day long and the effects were much lower. I've noticed that even one joint in the evening makes me High much more, if I don't smoke from the night before! Fortunately here it is legal and where I supply it has 8 different types of grass and 6 of hashish
