First smoked a J just over 10 years ago. Puffed here and there throughout the next few years, but started smoking daily 8 years ago. Haven't stopped more than a week or so since. My actualy high (initial buzz) or peak lasts for maybe the 1st 2-3 mins or so and the rest of the high eases up for the next half hour to hour. The inital high is the only time I still get a little paranoid, or wobly feeling. After that I'm fine though. I might have a little buzz that stays with me the next hour or so, but I feel fine and can function with ease.
