The packages state "Not for human consumption" for a reason. These are new compounds that are synthetically made. No one knows what the long term effects of doing these substances will be. Sure, you know the short term effects, but not long term. Weed has been around for a long time and everyone pretty much knows what the effects are. They haven't done any testing on this new stuff. If you guys want to be human guinea pigs that is fine with me, but you do it at your own risk. You do realize you are human guinea pigs don't you? The reason the disclaimer is on the packaging is so when crazy shit starts happening to people, the companies that make the stuff won't be liable for paying for your medical expenses. They will just say "It clearly says not for human consumption on the package, they misused the products, so they are liable for their own choices." You need to realize these companies don't give a shit about you. They care about making a profit. A lot of people try to rationalize what they do by saying things such as "Well it's really close to weed on the molecular level." That is stupid. Sugar and ethylene glycol(antifreeze) are really similar on a molecular level as well. Both taste sweet, but one can kill you, the other won't. THC and "synthetics" are not the same thing at all. They are completely different compounds, they might look similar, but anyone with a rudimentary knowledge of chemistry would know that all compounds are different, even if they "look" similar. Sure the synthetic might get you high like weed, but it is not weed. It just isn't. That is why it causes crazy shit to happen like increasing your heart rate to crazy levels. Look at cigarette smoking, no one knew it was dangerous for a long time. It took a while for the long term effects of cigarette smoking to come to the surface. Now everyone knows how dangerous it is. The same thing could very well happen with these synthetics. Like I said, they are very new compounds with no studies done on them, as to what long term effects will be. Anyone with half a brain would know to err on the side of caution when it comes to things that the health effects are still unknown. I know I will probably get flamed for this by the users of these products, but whatever, I'm just giving my 2 cents.
