Well ive been smokin for a few years now, but a year ago my bro gave me this mini bong type thing its about 6inches and holds very little water, and have been smokin ouatta that since. A few months ago I started to get breathing probs when i sleep, and now know its from the mini bong cuz when i smoke joints i can breath fine, but it wastes too much bud and is less effcient in getting me stoned. Well my quetion is should i buy a bubbler for about $100-120(can) or buy a Vaportech which would cost me about over $200(can), I dont really have a job so saving money is important. Which one should i get? I know that vaporizers are the healthiest, but maybe the bubbler could also help me breath better, I dont know. Any suggestions would be very much appreciated
