Drug recovery treatment will usually begin by weaning the individual off the substance to which they have become addicted.
In many cases, this will require the individual concerned going 'cold turkey', whereby they will simply cut the drug out of their lives with immediate effect, rather than slowly reducing their reliance on the drug.
Even mild, everyday drugs such as caffeine will induce withdrawal symptoms in those who regularly consume them when they decide to stop. Anyone who has ever tried to go from regularly drinking coffee to stopping completely will recognise the effects of withdrawal, such as irritability, tiredness and headaches.
How much more, then, must someone addicted to more dangerous drugs go through when attempting to kick their habit as part of their drug recovery treatment?
Cocaine addiction, for example, can bring on intense cravings, agitation, nausea and vomiting when someone is attempting to bring an end to their reliance on the drug.
Heroin can bring on similar withdrawal symptoms during drug recovery treatment, but these can also be accompanied by increases in respiration rate, heart rate and blood pressure - all of which can do lasting damage if not properly monitored.
This can be a painful and difficult process, which is why this form of drug recovery treatment is often best achieved at a rehab clinic, where experts can check on the patient's progress and provide them with the necessary support to help them through their addiction treatment.
