Many receptor-mediated events show the phenomenon of desensitization, which means that continued or repeated administration of a drug produces a progressively smaller effect. Desensitization is a reversible process, although it can take hours or days for receptors to recover after down-regulation.
Different drugs have varying risks, but some are common among psychoactive drugs. Some of these risks include heart issues, addiction, worsening symptoms of mental illness, and death.

LSD and other hallucinogens can cause a person to experience, hear, or see things that do not exist.
Differences in efficacy determine whether a drug that binds to a receptor is classified as an agonist or as an antagonist. A drug whose efficacy and affinity are sufficient for it to be able to bind to a receptor and affect cell function is an agonist. A drug with the affinity to bind to a receptor but adhd medication mistakes and dosage myths without the efficacy to elicit a response is an antagonist. After binding to a receptor, an antagonist can block the effect of an agonist. Tobacco is a plant grown for its leaves, which are dried and fermented before use. Nicotine is sometimes extracted from the plant and is used in vaping devices.

Kratom is consumed for mood-lifting effects and pain relief and as an aphrodisiac. A powerfully addictive stimulant drug made from the leaves of the coca plant native to South America. A person who takes a drug containing fentanyl is more likely to overdose if their body does not have sufficient tolerance for strong opioids.
In some instances, the same drug can cause a higher psychological addiction, and in others, the physical one is higher. Another factor to consider is the addiction risk of every drug. This focus area relates to the harmful effects and consequences of drug use which prompted the introduction of terms such as hard drugs and soft drugs.
