Which drug is often abused under the pretense of controlling weight?

Amphetamines are often abused under the pretense of controlling weight due to their stimulant properties, which can suppress appetite and increase metabolism. This appeal makes them attractive to individuals seeking rapid weight loss or enhanced performance. In some cases, prescription forms of amphetamines are used in weight management for conditions like obesity, but their potential for misuse leads some to illegally obtain and use them for their appetite-suppressing effects.

Marijuana typically does not have a direct association with weight loss and can even lead to increased appetite in some users. Methadone is primarily used in drug addiction treatment to help with opioid dependence and does not relate to weight control. Phencyclidine (PCP) is an anesthetic agent known for its hallucinogenic effects and is also not commonly linked to weight control goals.
