35 million Americans had substance use disorders in 2019. As common as addiction is, only 10% of addicts receive treatment. Addiction is a disease that can impact anyone, regardless of your family history, upbringing, or career path. Plenty of people seem to have everything together, but behind the mask, they hide their battle with addiction.

Addiction can happen to anyone with little warning. What can start as just trying something new with a friend or a prescription from a doctor can quickly become an addiction.

The most often abused drugs in the United States are alcohol, opiates, stimulants such as methamphetamines and cocaine, and benzodiazepines. The effects vary from drug to drug, each with its dangers, effects, and withdrawal symptoms.

Dependence on a substance can happen quickly, leading the user down a dangerous path of addiction where the user cannot function normally without it. For some users, withdrawals can be so severe that they have deadly consequences.

Risks Associated With Being High on Drugs

An incredible number of different health risks are taken on when someone starts getting high on drugs. Depending on the types of substances they are using to get high, the risks and effects can be relatively mild or potentially devastating and even deadly. Here, we cover some of the risks of different drugs.


Alcohol can cause serious problems in the short-term and the long term. In the short term, the risks of alcohol abuse include slurred speech, loss of coordination, inability to function in a socially acceptable way, and loss of bladder and bowel control. There is also a considerable difficulty in the alcoholic’s brain to make and retain memories.

In the long-term, alcohol abuse can cause various cancers, particularly in those that are high-functioning and maintain a heavy drinking habit for many years. Cases like these are also known for presenting with liver conditions and diseases. 

“Wet Brain” is a very high-risk condition for alcohol abusers. Wet Brain is where the brain sustains memory loss and eventually suffers irreversible brain damage due to years of consistent abuse.


Benzodiazepines, or “benzos,” are a class of drugs often used to manage anxiety and panic disorders. One of the most common benzodiazepines is alprazolam, which goes by the brand name Xanax. 

The side effects of this type of drug can be terrible. It can cause serious behavioral changes as well as changes in the sex drive. Benzos can often give a strong feeling of euphoria, but they can just as easily cause dramatic mood swings and irritability. 

Also impacted are the cognitive functions like memory, attention, and inhibition. The physical risks include dizziness, dry mouth, trouble maintaining an erection, fatigue, nausea and vomiting, slurred speech, and even seizures.

Opiates are a very large class of drugs derived from the opium poppy or synthetic variants. Opiates are central nervous system depressants as well as respiratory depressants. This means they slow down the user’s body and mind. Depending on how they are taken, opiates can have many different risks.

When snorted, there is a high risk of overdose since the drug enters the system extremely quickly, and if the user is not used to it, their body may not be able to handle it. Another risk of snorting opiates is the risk of chronic infections to the nasal and sinus tissues, which can lead to a large-scale breakdown of the tissue in necrosis.

Injecting is another popular method for taking opiates and comes with risks. Most significant are the risks from the actual injection, such as infection and vein damage. This is another method most at risk for an overdose since the drug is put directly into the bloodstream. Other risks of injection include the possibility of blood-borne pathogens from sharing used needles.


Stimulants like amphetamines are often prescribed to those with attention deficit hyperactivity disorder, or ADHD, to help mitigate the symptoms of the illness and achieve focus and concentration. However, they are also frequently abused by those with prescriptions and those without.

The most significant risks from taking stimulants come from altering the user’s brain chemistry, leading to chemical dependence. Since most stimulants act on neurotransmitters like serotonin, norepinephrine, and dopamine, using them for long periods then stopping can lead to serious health problems. 

These problems can include heartbeat irregularities, impotence, weight loss, high blood pressure, difficulty reaching orgasm, nausea and vomiting, muscle tremors, agitation, anxiety, headache, and other symptoms.

Additionally, since the dopamine receptors can become burnt out, those who abuse stimulants may discover that when they stop using them, they have difficulty finding pleasure in things they once loved. Again, this is due to the chemical dependency they develop and the devastating effect on the overall health of the brain’s reward and pleasure centers.
