The most dangerous aspect of multiple depressant use is the additive factor.
True. Any drugs that are mood-alterating have an addiction rate of not less than 15%
The chemical engineer is correct! So, TRUE.
It’s the additive, or SYNERGISTIC factor. Basically, synergy means that 1+1=3. Depressant drugs combined can depress breathing significantly to the point where are person goes without oxygen and dies.
I am guessing that you refer not to addiCtion, but to how the metabolic effect of doses of different drugs interact.
To me the problem would be one of nonlinear effect, ie a synergistic reaction, not a linearly additive metabolic effect. But I am a chemical engineer, not a doctor, so the nomenclature may well be different.
What I think may be an illustrative hypothetical: If a doc needed to give someone a dose of depressant, but the cupboard were almost bare, and the doc in desperation gave half a dose of this med and half a dose of that one, and the patient reacted like they had gotten ten doses of either….
I think it’s a high risk factor but not the highest. I would say false. There are other more serious side effects such as increased risk for suicide, serious withdrawal symptoms, and it’s ineffectiveness. Being addictive is not as much a death warrant as increased risk of suicide. They also say some of these can cause suicidal or homicidal rages which, too, is more serious. I would say false.
