If someone is looking for a cheap addiction then "no NPS* talk" on Nexus won't stop him.

If someone is using the "they do it, why shouldn't I" logic then "no NPS talk" on Nexus won't stop him.

Dozens of sites offer more information on use (and abuse) of NPS than Nexus.

It is my experience that if someone would start talking about combining multiple NPS in the chat he would be asked if he has looked into the dynamics of such polydrug use and is aware of potential dangers.

History of a substance does not automatically correlate with safety or amount of studies done. I doubt any drug will receive as much attention from the scientific community as LSD did (in the past).

What would be your proposed limitations ? No RC/opiate talk in the chat at all ? Mind that this won't stop users from taking NPS/opiates it will just redirected them to another site. The question then is if the policy of that site offers the same quality information in terms of effects, benefits and dangers of the particular NPS/opiate as Nexus does ?

*Novel Psychoactive Substances AKA "research" chemicals
