Detailed explanation-1: -Hallucinogens are a type of drug that changes a person’s perception of reality. Also known as ‘psychedelic drugs’, hallucinogens make a person see, feel and hear things that aren’t real, or distort their interpretation of what’s going on around them. Some are quick acting, others take longer to take effect.
Detailed explanation-2: -That hallucinogens ‘stimulate’ serotonin 2A receptors means that they mimic the action of serotonin at the receptor by binding to it, altering its conformation or ‘shape’, and ultimately altering the internal conditions and therefore behaviour of the neuron it sits on.
Detailed explanation-3: -Common hallucinogens include the following: ayahuasca, DMT, D-lysergic acid diethylamide (LSD), peyote (mescaline), and 4-phosphoryloxy-N, N-dimethyltryptamine (psilocybin).
