Benzodiazepines have a sedating effect but because of their potential for producing agitation and tantrums can also cause a lot of unrest. But the greatest danger lies in fatal combinations:

1 + 1 = 3 Certain benzodiazepines - particularly the fast-acting kind - are popular in the drug world because of the mellow 'high' they give. Used together with other drugs, however, they can be life-threatening. The effects of heroin and other opiates, for instance, are intensified with benzodiazepines, creating the known 1 + 1 = 3 effect. With a little bad luck the 1 + 1 = 4 effect is induced, or the user may die from heart failure.

Alcohol

Combined with alcohol, benzodiazepines can be fatal. One might well survive a 'good' dose of Valium but taken in combination with alcohol one can fall into a coma.

Are benzodiazepines addictive?

Yes. Particularly in psychological terms, there is a potential for a quick and heavy dependence. Also with benzodiazepines, tolerance develops: An increasing amount is needed to maintain the same effect.

Can the use of benzodiazepines lead to aggression? 

Yes. Particularly in combination with alcohol or when the substance is discontinued after prolonged use. Of all benzodiazepines, Rohypnol has the worst reputation. This substance can induce aggressive and seemingly unscrupulous behaviour when taken in high doses. The individual loses his/her inhibitions and most of the time cannot remember anything afterwards.
