of recreational drug use.
Some of the most common theories are: genetics, personality type, psychological problems, self-medication, sex, age, depression, curiosity, boredom, rebelliousness, a sense of belonging to a group, family and attachment issues, history of trauma, failure at school or work, socioeconomic stressors, peer pressure, juvenile delinquency, availability, historical factors, or socio-cultural influences.

.
Regardless of genetics, mental health, or traumatic experiences, social factors play a large role in exposure to and availability of certain types of drugs and patterns of use.[
According to addiction researcher Martin A. Plant, some people go through a period of self-redefinition before initiating recreational drug use.][ They tend to view using drugs as part of a general lifestyle that involves belonging to a subculture that they associate with heightened status and the challenging of social norms.][ Plant states: "From the user's point of view there are many positive reasons to become part of the milieu of drug taking. The reasons for drug use appear to have as much to do with needs for friendship, pleasure and status as they do with unhappiness or poverty. Becoming a drug taker, to many people, is a positive affirmation rather than a negative experience".][

is harmful to a user and is measured in several ways, such as by addictiveness and potential for physical harm. More harmful drugs may be colloquially referred to as "hard drugs", and less harmful drugs as "soft drugs". The term "soft drug" is considered controversial by critics as it may imply that soft drugs cause no or insignificant harm.[
]
Responsible use
The concept of "responsible drug use" is that a person can use drugs recreationally or otherwise with reduced or eliminated risk of negatively affecting other aspects of one's life or other people's lives. Advocates of this philosophy point to artists and intellectuals who have used drugs, experimentally or otherwise, with few detrimental effects on their lives. Responsible drug use becomes problematic only when the use of the substance significantly interferes with the user's daily life.
Responsible drug use advocates that users should not take drugs at the same time as activities such as driving, swimming, operating machinery, or other activities that are unsafe without a sober state. Responsible drug use is emphasized as a primary prevention technique in harm-reduction drug policies. Harm-reduction policies were popularized in the late 1980s, although they began in the 1970s counter-culture, through cartoons explaining responsible drug use and the consequences of irresponsible drug to users. Another issue is that the illegality of drugs causes social and economic consequences for users—the drugs may be "cut" with adulterants and the purity varies wildly, making overdoses more likely—and legalization of drug production and distribution could reduce these and other dangers of illegal drug use. Harm reduction seeks to minimize the harm that can occur through the use of drugs, whether legal (e.g., alcohol and nicotine), or illegal (e.g., heroin and cocaine). For example, people who use drugs intravenously (e.g., cocaine and heroin) can reduce harm to themselves and members of the community through proper injection technique, using new needles and syringes every time, and properly disposing of all injecting equipment.

School-based programs are the most commonly used method for drug use education; however, the success rates of these intervention programs is highly dependent on the commitment of participants, and is limited in general. Studies have also shown that home intervention is also effective in decreasing the appeal of drugs.

Beginning in 1982, the Drug Enforcement Administration turned increased attention to marijuana farms in the United States, and there was a shift to the indoor growing of plants specially developed for small size and high yield. After over a decade of decreasing use, marijuana smoking began an upward trend once more in the early 1990s, especially among teenagers, but by the end of the decade this upswing had leveled off well below former peaks of use.[

Types
Depressants
Depressants are psychoactive drugs that temporarily diminish the function or activity of a specific part of the body or mind. Colloquially, depressants are known as "downers", and users generally take them to feel more relaxed and less tense. Examples of these kinds of effects may include anxiolysis, sedation, and hypotension. Depressants are widely used throughout the world as prescription medicine

, a characteristic euphoria at moderate doses. High dosages taken to induce recreational drug effects may lead to overdoses. Antihistamines are also consumed in combination with alcohol, particularly by youth who find it hard to obtain alcohol. The combination of the two drugs can cause intoxication with lower alcohol doses.
Hallucinations and possibly delirium resembling the effects of Datura stramonium can result if the drug is taken in much higher than therapeutic doses. Antihistamines are widely available over the counter at drug stores (without a prescription), in the form of allergy medication and some cough medicines. They are sometimes used in combination with other substances such as alcohol.
The most common unsupervised use of antihistamines in terms of volume and percentage of the total is perhaps in parallel to the medicinal use of some antihistamines to extend and intensify the effects of opioids and depressants. The most commonly used are hydroxyzine, mainly to extend a supply of other drugs, as in medical use, and the above-mentioned ethanolamine and alkylamine-class first-generation antihistamines, which are – once again as in the 1950s – the subject of medical research into their anti-depressant properties.
For all of the above reasons, the use of medicinal scopolamine for recreational uses is also observed.
