Respected sir/madam,
I know there are people looking to deal with the stress in their lives in a way that does not show up on a drug test. That is not a reason to trust your lives to a lying con man who could not care in the least if you end up on a slab in the morgue from using his product. Besides, Redwood Toxicology Laboratory has developed an accurate test for JWH compounds that is available right now to anyone who cares to use it for drug screening. So that kind of takes most of the appeal away. What are you left with then? A marijuana substitute that is far more dangerous and twice as expensive - and it could send you to the emergency room.
There are those that will respond and make ridiculous comparisons between K2 and alcohol to make you feel K2 is safe. Alcohol has a far longer and more widespread history of abuse and exhaustive studies have been done on its effects on humans. We know the downside of its effects and prolonged usage. Not so with JWH compounds.
When the man who invented it (John W. Huffman) says people are idiots for using it,
I trust his word far more than that of an internet con man with a history of ripping people off. So should you.
