Explanation:

For Question 7: Cocaine is a stimulant. Its effects include vasoconstriction (which can lead to nosebleeds), increased heart rate and blood pressure (causing irregular heartbeats, risk of heart attacks and strokes), and neurological effects like anxiety and paranoia. Fentanyl is an opioid (depressant - pain relief, sedation), LSD is a hallucinogen (altered perception, not typical stimulant - like physical effects here), and ketamine is a dissociative anesthetic (not a stimulant with these specific symptoms).
For Question 8: Methamphetamine is a stimulant. Chronic use causes skin picking (due to formication - false sensation of bugs on skin) leading to sores, severe dental problems ("meth mouth" - dry mouth, bacteria overgrowth), and extreme weight loss (suppresses appetite, increases metabolism). LSD is a hallucinogen (no typical physical effects like rotting teeth), cocaine (while a stimulant) doesn't have the "itchy skin - sores from scratching" as a hallmark chronic effect like meth, and ecstasy (MDMA) has different effects (euphoria, empathy, not rotting teeth as a main chronic sign).
