Final answer:
The substance that shows strong physical but little psychological dependence among the provided options is LSD. LSD causes hallucinogenic effects, but it does not generally result in physical withdrawal symptoms like heroin or cocaine do.
Step-by-step explanation:
Among the options given (Cocaine, Heroin, Nicotine, LSD) for the substance that shows strong physical but little psychological dependence, the correct answer is LSD. LSD (Lysergic acid diethylamide) is known primarily for its hallucinogenic effects and can cause significant changes in perception, mood, and thought. Unlike cocaine and heroin, which can create both strong physical and psychological dependence, LSD is associated more with psychological effects. It does not typically produce the same kind of physical withdrawal symptoms that drugs like opioids (heroin) or stimulants (cocaine) do.
Psychological dependence refers to drug craving and an emotional need for the drug, often to relieve psychological distress. Physical dependence, on the other hand, refers to the body's adaptation to a substance, leading to withdrawal symptoms upon cessation. LSD is less likely to cause physical dependence, but its profound impact on consciousness can lead to mental and emotional reliance.
To manage physical dependence on drugs like heroin, a patient might be prescribed methadone, which is a psychoactive drug that reduces both cravings and withdrawal symptoms without causing the same level of addiction.
