There are thousands of legal and illegal drugs available in the market. There are several ways to classify drugs, including by chemical classification of drugs, legal classification of drugs and its effects on the mind and body.

What Are Classifications Of Drugs?

Classification of drugs by chemical similarities is useful because drugs that are chemically similar often have similar impacts and risks. A person who is addicted to the drug is also more likely to abuse and become addicted to another drug if it is chemically similar. Sometimes the same treatment is often effective for chemically similar drugs. However these generalities, chemically similar drugs may have very different legal and medical impacts.

Effects Of Drugs

Some people classify drugs by how they impact mentally and physically. Eg, some drugs have a tendency to make a user active and energetic while others make you feel relaxed and calm. It is especially common among drug users and those who work closely with drug users. Many of these drugs classifications have little basis in chemical similarity or legal outcomes, although there is often overlap.

Legal Classification Of Drugs

Legal classifications of the drugs are generally based on the perceived medical value of a drug and its perceived risk and danger. It means that the same drug may be classified differently under two schemes or two systems may use categories with the same name. It’s impossible to create a “definitive” set of drug classifications due to these disagreements. However, some of the most common are listed below.

Chemical Classifications Of Drugs

Which enables opioids to serve as powerful pain killers it can cause feelings of intense pleasure, leading to addiction. Opioid addiction is one of the most serious problems faced by America. Heroin, fentanyl, oxycodone are Some of the famous opioids.


Alcohol is the most widely abused substance across the world as well as the USA. Legal to some extent in all 50 states, alcohol impacts numerous body systems, which in turn causes numerous effects in users. Alcohol helps to create feelings of euphoria and lowers inhibitions, but it also severely impairs judgment, perception, and reaction times. There are many forms of alcohol, including: beer, wine, liquor, brandy and opioids.

Benzodiazepines Drugs

Benzodiazepines also known as benzos, a class of drugs that function by interacting with the neurotransmitter gamma-aminobutyric acid (GABA-A). Each Benzo interacts with GABA-A differently, which is why each one impacts the brain and body differently. Benzos are prescribed to treat a wide variety of psychiatric and sleep conditions, but they are commonly abused. Benzos are highly addictive, and can cause numerous problems when not used as intended. Ativan, valium, xanax are the most popular benzos.

They are still used for anesthesia and treatment of a number of conditions such as epilepsy and headaches. Barbiturates are highly addictive, and they also present a very high overdose risk because they cause many body systems to shut down. Amytal, luminal, pentobarbital are kind of barbiturates drugs.

Cannabinoids Drugs
