ive struggled with the same question. in my case, my friends were smoking, but i didnt know whether to quit because i would have fun while smoking with them then when coming down i would get depressed since i was going through a rough time in my life. I've learned you just gotta do what suits you best. A break is good for a while because while stoned its easy to "lose track of yourself", and to reunite with reality is always a good thing. Plus a good break guarentees you a stronger high after you start back up again.. cant complain about cheap highs lol
