Social interaction where people respond to shit, can help smoking succession
27
Stimulants
Stimulate and heighten activity in the body, increase heart rate, blood pressure, mood, restlessness Decreases sleep interferes with **reuptake of dopamine** (allow dopeimine to last longer) Increases **release of dopamine**
28
Cocaine
Feel Alert, energy, sociable, feeling amazing Can lead to Parania, psychotic, violence Blocks reuptake of dopamine

31
Alcohol
Small doses: feel relax, elevate mood, impart judgement, Large doses: sedating and depressant effects more apparent, Brain centre becomes depressed Increase **GABA** Decrease **Glutamate**
32
Opiates (narcotics)
Relieve pain and induce sleep (Heroin, morphine, codeine, oxycodone)
33
Mu opioid Receptor
Opiates bind to and stimulate receptors to relieve pain, Heroin works on mu and dopamine receptors
34
Hallucinogens (psychedelics)
Alters cognition mode and perception Interferes with **serotonin and dopamine** LSD, mushrooms, MDMAish
35
Marijuana
THC: relaxed mental state, uplifted mood, distortions in perception or cognition. Decreases in reaction time, motor coordination, memory **Hippocampus (memory)** CBD: Anti anxiety, anti-inflammatory, anti-psychotic
