Negative Health Effects of Various Illegal Drugs

The Health Effects of Marijuana

Proponents of marijuana legalization and pot smokers, in general, tend to believe there is no harm in using marijuana, but scientific research tells us differently. Studies have shown that smoking weed can have negative effects on the brain, the heart, and the lungs.

Although no link has been confirmed between smoking marijuana and the risk of developing cancer, marijuana smoking leads to the significant deposition of tar and carcinogens.

Effects of Methamphetamine

The health effects of methamphetamine use may be the most noticeable and visible of any of the commonly abused illegal drugs because it has such a dramatic effect on the outward appearance of people who chronically use the substance. After a relatively short period of use, methamphetamine will begin to show on the faces of some users and begin to rot their teeth, known as "meth mouth."

Meth is a stimulant, which affects the body's central nervous system. It's highly addictive ​and cheaper than many other street drugs, which is why so many get hooked so easily.

The Health Effects of Cocaine

The effects of cocaine may not be as immediately noticeable as those of meth use, but they can be just as devastating. Although cocaine overdose is rare, the use of the drug can lead to an increased risk of heart attack and stroke. Cocaine stimulates the central nervous system and affects how the brain processes dopamine. Other health problems can occur depending on how the drug is used: snorted, ingested, or injected.

Health Effects of Ecstasy

Although MDMA (also called ecstasy) is a so-called designer drug, negative health effects associated with its use are similar to those experienced by amphetamines and cocaine users.

MDMA can cause a long list of physical problems, which can include sleep disruption, severe anxiety, nausea, blurred vision, increased heart rate, and high blood pressure. It can also lead to increased body temperature that can be fatal. Another danger of ecstasy use is that it is often mixed with other drugs, which can have unexpected consequences.

The Health Effects of Heroin

Some of the health effects associated with heroin use are not due to the use of the drug itself but related to the manner in which it is used. People who inject heroin can suffer many negative health effects related to infections that develop due to the use of non-sterile injection techniques. It's easy to overdose on heroin, which is often cut with other toxic substances.

Heroin is a highly addictive drug in the opioid family, with withdrawal symptoms beginning shortly after the drug is taken. Studies have also found that heroin use can lead to a loss of the brain's white matter, which plays a role in a variety of important brain functions.

Effects of LSD

There are really very few studies about the long-term health consequences associated with the use of LSD. Most of the physical effects produced by LSD use are relatively mild; its psychological effects are much more dramatic.

The main problem with LSD use is that its effects are unpredictable: A regular user of LSD can suddenly experience an acute adverse reaction, including severe anxiety, paranoia, and panic attacks, known as a "bad trip," at any time.
