Yeah i used to smoke hash at least 15x a day for like 3 years. I smoked a few times a day the two years before that. It definately enhanced the quality of life by 100% but after that much constant smoking you realize that it does start to get better when you don't make it a priority. Its only a priority when i'm snowboarding now that is essential. The thing i don't like other than how it gets you tired is how it steals your memory and that is one of the most important things.
