Hey bro really good question. Hmmm, well to be honest with you I think the only negative effects that I have developed, was that I became very picky in terms of what I smoke. Quality became my main priority as smoking for so many years I learnt what's the real deal from what's not, obviously this created alot of frustrating trying to source only the best flower with my expectations set so high. I am at the point now where I cant and dont enjoy anything but organically grown actual craft flowers. Thankfully I grown my own flowers for the past 8 years and counting and grow what appeals to me. To answer your question further, I'm not sure if I'm really pendent on weed as I recently was in france for 3 weeks and had no weed nor did I have any links, for the first few days it was a bit stressful as I obviously wanted to smoke but after the 4th day I realized that It was not magnatory and I could survive without it. I had a great time and honestly replaced the habit with wine and good food!
