What is considered to be a drug?
There are many types of hallucinogenic drugs. There are several categories of hallucinogen. The three main categories of hallucinogenic drugs are the psychedelics, dissociatives and deliriants. Some famous psychedelics include LSD-25, Psilocybin, Mescaline, DMT, 2C-B and Cannabis. Some famous dissociatives include Ketamine, Dextromethorphan, Nitrous Oxide and PCP. Famous deliriants include Atropine, Scopolamine and Diphenhydramine. The psychedelic hallucinogens mostly work by affecting serotonin receptors in the brain. Dissociatives affect NMDA, Dopamine, and/or Opioid receptors. Deliriants typically affect Acetylcholine. Each of these three categories has many, many known drugs in it and there will be more discovered in the future. Some occur naturally in nature, some are created synthetically, others are modified from their natural form to become semi-synthetic. In addition, each category of hallucinogen contains drugs with distinctly different effects than the drugs from another category. Additionally, drugs of the same category can have different effects.

Sort of. Caffeine can give you a body rush and make you feel energetic. If you are a lethargic person this could be considered pleasurable. Caffeine has also been found to be mildly dopiminergic, generally with the first dose of the day. So when caffeine starts entering your system in the morning it could slightly boost your mood.

What is the main idea of caffeine?
Caffeine is a bitter white crystalline xanthine that acts as a psychoactive stimulant drug and a mild diuretic (speeds up urine production) in humans and other animals. Caffeine was discovered by a German chemist, Friedrich Ferdinand Runge, in 1819. He coined the term "kaffein", a chemical compound in coffee, which in English became caffeine. Caffeine is also called guaranine when found in guarana, mateine when found in mate, and theine when found in tea; all of these names are synonyms for the same chemical compound.
Caffeine is found in varying quantities in the beans, leaves, and fruit of some plants, where it acts as a natural pesticide that paralyzes and kills certain insects feeding on the plants. It is most commonly consumed by humans in infusions extracted from the beans of the coffee plant and the leaves of the tea bush, as well as from various foods and drinks containing products derived from the kola nut. Other sources include yerba mate, guarana berries, and the Yaupon Holly.
In humans, caffeine is a central nervous system (CNS) stimulant, having the effect of temporarily warding off drowsiness and restoring alertness. Beverages containing caffeine, such as coffee, tea, soft drinks and energy drinks enjoy great popularity. Caffeine is the world's most widely consumed psychoactive substance, but unlike most others, it is legal and unregulated in nearly all jurisdictions. In North America, 90% of adults consume caffeine daily. The U.S. Food and Drug Administration lists caffeine as a "Multiple Purpose Generally Recognized as Safe Food Substance.One 2008 study suggested that women consuming 200 milligrams or more of caffeine per day had about twice the miscarriage risk as women who had none, while another 2008 study found no link between miscarriage and caffeine consumption.

In humans it acts as central nervous system (CNS) stimulant.
