Benzodiazepines, prescription drugs used to treat anxiety and seizures, work by calming the brain, and promoting a tranquil mood. They are fast acting and, like opioids, lead to dependence and addiction. Cocaine and amphetamines also carry significant risks for dependence, addiction, and adverse long-term effects.
Prescription amphetamines (Adderall), are commonly used for attention deficit disorder because of the calming and focusing effects but can be misused by taking increased doses or without a prescription. Likewise, cocaine and methamphetamine will cause an individual to seem extremely alert and have increased energy along with increased heart rate and blood pressure. These drugs have harsh effects once they run their course, with users experiencing severe anxiety, irritability, and insomnia.
