R78.3: Finding of hallucinogen in blood

Hallucinogens are substances that alter how you think and behave. These include drugs such as LSD, for example. However, this also includes certain plants such as the fly agaric. The fact that you experience your environment differently than normal by taking these substances is typical for hallucinogens. Sometimes this puts both you and others at risk.
