Psychoactive Research chemicals are new synthetic substances that are structurally similar to the original drug, while being functional analogs. Research on the effects of, and treatment for, abuse of these drugs is limited due to the fact that they’re fairly new and have avoided mainstream notice. Research chemicals do not have a lot of human consumption data, and thus harm-reduction and special care should be taken if choosing to ingest them.

Psychedelics are drugs which cause profound changes in a one’s perceptions of reality, otherwise known as hallucinations. While under the influence of hallucinogens, users might see images, hear sounds or feel sensations. These chemicals offer some of the most intense psychological experiences and care should be taken when ingesting them.

Experimental drugs have extremely limited human consumption data. There is not enough reliable information about this substance. This is most likely because the substance is is not very old. Information on these substances is limite and incomplete. Please be cautioned. Always practice harm reduction.

Disclaimer: Psychedelic drugs offer some of the most power and intense psychological experiences. Additionally these substances are illegal in many places. We understand that even though these substances are illegal, their use occurs frequently. We do not condone breaking of the law. By providing accurate information about these substances, we encourage the user to make responsible decisions and practice harm reduction.

Practice Harm Reduction. Proceed with Caution.
