What are the positive effect of drug?

Pleasure is an obvious part of drug use and the short-term physical benefits are well known. Drugs can cause a “high”, energize people, make them feel good, reduce stress and help them sleep. The social benefits of drug use are more complex to quantify. Medications are chemicals that affect the body and brain.

Different medications can have different effects. Some drug effects include health consequences that are long-lasting and permanent. They may even continue after a person has stopped taking the substance. Different types of medications affect the body in different ways, and the effects associated with medications may vary from person to person.

How a drug affects a person depends on a variety of factors, such as body size, general health, the amount and concentration of the drug, and whether there are any other drugs in the system at the same time. It's important to remember that illegal drugs are not controlled substances and, therefore, quality and concentration may differ from batch to batch. For example, a person who needs to get higher grades in school, who studies better while using a certain medication, may continue to receive boosters to use it, since drug use helps them study longer and gives them better grades. Alternatively, a person struggling with depression may discover that using a medication can provide sufficient relief to temporarily calm their sad or sad mood and, depending on the substance, continue to consume it.

In the first example, adding the drug leads to better (positive) scores and reinforces further use of the drug. In the last example, the use of the drug eliminates (negative) the aversive situation, depression, which reinforces the subsequent use of the drug. Both result in the maintenance or increase of drug use.
