The initial feeling of relaxation and happiness, followed by slurred speech, difficulty concentrating, irritability, and eventually falling into a deep sleep, are all common effects of barbiturates. Marijuana may produce relaxation and difficulty concentrating, but it is unlikely to cause irritability and aggression. Amphetamine can produce irritability, but it is unlikely to cause such profound sedation. LSD does not typically produce sedation or irritability.
