Well, I would like to give some warning on these synthetic cannabinoids.. I had quite a lot experience with the "real" stuff, been smoking almost daily in large amounts the last 14 years, including several trips to amsterdam to check out the strongest they have, I must say that these new "legal highs" are quite different.. The turn is quite similar to the "real", whereby the one "legal high" I recently used (Bonzai Citrus) was "stronger" in a certain way, especially to the heart rate (pulse) but not as complete in the high feeling compared to the "real". Anyway there were several side effects I did not know from real weed even if overdosed, these were especially strong heart pain in the beginning and some effects even two days after smoking like feeling dizzy and weird. I guess no one knows what these drugs really do to your body and i guess they are a lot more dangerous than real weed. No one ever died of smoking too much of the real weed, I guess everyone here knows that if smoking or even eating too much weed, your heart can also go crazy and you get paranoid, but this is somehow in another way. Well, you should keep in mind that THC (the real) is only a PARTIONAL agonist of the CB-receptors of your body, whereas several synthetic cannabinoids are FULL agonists. As a result in my opinion it would not be unlikely if someone some day would really die by e.g. a heartattack by an overdose of these synthetic cannabinoids. These synthetic cannabinoids are often completely different in their molecule structure compared to THC, they only mimic the effects of real THC as concerns the cannabinoid receptors of your body so that you have a similar high, but no one knows about their metabolites and which toxicity they have to your body, liver, lungs, etc. at all.. So i advise on everybody to keep away from this synthetic stuff if possible!
