Depressant drugs can cause effects closely resembling alcohol intoxication. As with alcohol intoxication, the operation of an automobile and other machines is especially dangerous. Motor coordination and visual perception may be greatly impaired. These effects are intensified in higher doses. In other words, the more you take, the more depressed your system becomes.
Different drugs are lethal in different amounts or in different combinations.
A regular user of depressant drugs over a long period of time may develop tolerance to the effects of these drugs. This individual may require an increasing dose to produce the desired effects. Kicking the Habit Dependence on depressant drugs is potentially one of the most dangerous of all chemical dependencies. If a person abruptly stops using a depressant drug, progressive restlessness, anxiety, irritability and possibly delirium and convulsions may occur. These symptoms may be fatal without proper medical attention.
