Drug rehabilitation services can be a turning point for someone who may have tried to end drug or alcohol use by themselves, but did not have success staying abstinent. The main reason individuals need drug rehabilitation services is simply because remaining abstinent isn't just dependent on overcoming immediate physical obstacles. Those who make use of drug rehabilitation services can take advantage of a variety of treatment options which will help them resolve problems in life which are more environmental, emotional and even psychological. As an example, studies have shown that substance abuse can often be brought about by purely environmental factors, such as turmoil, failure, or losses in one's life. There may be a co-occurring mental health disorder which must be addressed concurrently in drug rehabilitation services, and when not addressed most individuals will relapse in short order. While it will take a lot of time to fully reap the benefits of drug rehabilitation services, individuals who only detox and take part in no further treatment fare just as well as someone who received no drug rehabilitation services. Long-term inpatient or residential drug rehabilitation services are the most optimum drug rehabilitation programs for those hoping to have a full recovery and be able to make a fresh start.
