Drugs

Cocaine interferes with dopamine transport by blocking its reuptake, increasing dopamine levels in synapses (causing euphoria).

• (A) Acetylcholine: Not directly affected by cocaine.
• (B) Serotonin: Targeted by drugs like SSRIs, not cocaine.
• (C) GABA: Inhibitory neurotransmitter, unrelated to cocaine’s mechanism.

Morphine is a powerful pain-relieving medication classified as an opiate narcotic. It is derived from the opium poppy plant and is commonly used for the treatment of severe pain, such as that experienced after surgery or in individuals with advanced stages of certain medical conditions.

Opiate narcotics, also known as opioids, act on the opioid receptors in the brain and body, producing analgesic (pain-relieving) effects. They can also induce feelings of euphoria and sedation, which can lead to their misuse and addiction.

LSD (lysergic acid diethylamide) is a hallucinogenic drug, not an opiate narcotic. Barbiturates are a class of central nervous system depressants that are used as sedatives or hypnotics but are not opiate narcotics. Amphetamines are stimulant drugs that increase alertness and energy levels but are not opiate narcotics either.

Anabolic steroids are synthetic variations of the male hormone testosterone. When used by females, they can lead to a range of undesirable effects due to the androgenic properties of these substances. One of the most notable side effects is masculinization, which involves the development of masculine characteristics.

Common masculinizing effects of anabolic steroid use in females may include:

Deepening of the voice

Increased facial and body hair growth (hirsutism)

Enlargement of the clitoris

Disruption of the menstrual cycle

Decreased breast size

Changes in body shape (increased muscle mass and decreased body fat)

It's important to note that the use of anabolic steroids in females is typically associated with higher doses or prolonged use beyond therapeutic levels. These substances are often abused by athletes or individuals seeking to enhance their physical performance, which further increases the risk and severity of side effects. Therefore, the use of anabolic steroids should be closely monitored and guided by medical professionals to minimize potential harm.

Statement I: "Morphine is obtained by acetylation of Heroin" - Incorrect. Heroin is produced by acetylation of morphine, not vice versa.

Statement II: "Cannabinoids affect cardiovascular system" - Correct. Cannabinoids, particularly THC (tetrahydrocannabinol), can affect the cardiovascular system. The effect varies and may include increased heart rate, changes in blood pressure, and potential risks for individuals with pre-existing heart conditions.

The correct evaluation is: (C) Statement I is incorrect and Statement II is correct.
