There are many factors to consider when it comes to the question of whether drug rehab will work or not? One of the most significant factors is the length of time an addict has been using the drug. Another significant factor is the type of drug addiction, as certain addictions, such as cocaine, can be more difficult to deal with. Other factors that should be taken into account are the type of drug rehabilitation centre utilised, the duration of time spent recovering, as well as the after care or long term support once addiction rehab is completed.

Almost every addict has the potential to recover, however, very few quit without a relapse. The longer an addict remains in a drug rehab programme, the more likely they are to recover. This means that even after an intense drug rehabilitation programme has been completed successfully, a patient must commit to a lifetime of recovery.

Studies have concluded that residential drug rehab centres that offer three-month long programmes have a higher success rate than centres that offer only one-month residential programmes. It is for this reason that most in-patient programmes offer three-month drug rehab residency.

The least effective drug rehab centres are the ones that offer short-term detoxification programmes such as interventions. These types of rehab treatment programmes will admit an addict into a hospital for several days to deal with the physical withdrawals of the drug, however, this has proven non-effective.
