In case something bad happens our minds want us to be ready. iv. Problem solving model – instead of just consolidating, you are also solving. V. Psychoactive Drugsa. Stimulants – fire you up. i. Caffeine, nicotine, cocaine, amphetamines b. Depressants – reduce CNS activityi. Alcohol, barbiturates, benzodiazaprenes. c. Opioids – reduce paini. Opium, heroin, morphine. d.
