For users who take high doses of ecstasy, this can cause permanent nerve damage, especially to serotonergic neurons. Serotonergic neurons are responsible for producing serotonin, so permanently damaging them can result in a loss of connection between these neurons and can cause depression and anxiety. Deficits in short-term memory, executive control, and learning have been observed in association with ecstacy, as well as increased impulsivity. Some studies have found that it is possible for these issues to persist in abstinence, even up to 18 months.

Treatment with medicines

In the year 2011, around $267 million dollars of hospital services were attributed to dealing with substance abuse problems. The majority of these hospital costs in 2011 were related to issues with alcohol. Additionally, in 2014, Canada also allocated almost $45 million towards battling prescription drug abuse, extending into the year 2019. Most of the financial decisions made on substance abuse in Canada can be attributed to the research conducted by the Canadian Centre on Substance Abuse which conduct both extensive and specific reports. In fact, the CCSA is heavily responsible for identifying Canada’s heavy issues with substance abuse. Some examples of reports by the CCSA include a 2013 report on drug use during pregnancy and a 2015 report on adolescents’ use of cannabis.

When someone is addicted to drugs or alcohol, they feel a sense of comfort they haven’t been able to get elsewhere. Inevitably, this feeling is replaced by guilt and shame as they sober up and face the consequences of their actions. However, the weight of these feelings forces them to seek comfort in substances.

Behavioral Effects

This can actually change how the brain performs and interfere with a person’s ability to make choices. Over time, this behavior can turn into a substance dependency or drug andalcohol addiction. All drugs–nicotine, cocaine, marijuana and others–affect the brain’s “reward” circuit, which is part of the limbic system. Drugs target this system, which causes large amounts of dopamine—a brain chemical that helps regulate emotions and feelings of pleasure—to flood the brain. This flood of dopamine is what causes a “high.” It’s one of the main causes of drug addiction. Signs and symptoms of inhalant use vary, depending on the substance.

Alcohol and drug abuse can make symptoms of a mental health problem worse. Substance abuse may sharply increase symptoms of mental illness or even trigger new symptoms. Abuse of alcohol or drugs can also interact with medications such as antidepressants, anxiety medications, and mood stabilizers, making them less effective at managing symptoms and delaying your recovery. A number of medications have been approved for the treatment of substance abuse. These include replacement therapies such as buprenorphine and methadone as well as antagonist medications like disulfiram and naltrexone in either short acting, or the newer long acting form. Several other medications, often ones originally used in other contexts, have also been shown to be effective including bupropion and modafinil. Methadone and buprenorphine are sometimes used to treat opiate addiction.

In some cases, substance-induced psychiatric disorders can persist long after detoxification, such as prolonged psychosis or depression after amphetamine or cocaine abuse. A protracted withdrawal syndrome can also occur with symptoms persisting for months after cessation of use. Benzodiazepines are the most notable drug for inducing prolonged withdrawal effects with symptoms sometimes persisting for years after cessation of use. Both alcohol, barbiturate as well as benzodiazepine withdrawal can potentially be fatal. Abuse of hallucinogens, although extremely unlikely, may in some individuals trigger delusional and other psychotic phenomena long after cessation of use.
