Doing this can carry a lot more risk than just using a single drug at a time. This can also exist if you are mixing prescription drugs as well. Or if you are mixing drugs and alcohol together. Doing this may lead to the likelihood of overdose being much higher.
Poly drug use normally results in accidental overdoses. This could be what happened to Anna Nicole Smith, the actress and Playboy model. Because of her cocktail of prescription drugs she may have accidentally overdosed. The danger of overdosing with this type of drug use is high. The problem is when prescription drugs are being prescribed by more than one doctor it can be difficult to anticipate the kind of reaction the patient will have.
Drug rehab may be necessary to get off this kind of cycle. Drug addiction treatment is likely in this kind of drug use as well.
Please contact a drug treatment center or drug rehab for more information regarding the dangers of mixing drugs and alcohol.
