There are many different types of substance abuse rehabilitation centers in Denver which alcohol and drug addicted people can be helped from. For example, there are substance abuse treatment centers which cater to a treatment client with a very brief case of alcohol and drug abuse and would potentially find luck at a short term drug and alcohol treatment facility which will require the person to remain in rehab for 4 weeks or less. Then there are much more intensive and long term drug and alcohol abuse rehab facilities which involve a stay of 3 months or even longer in some cases, depending on the individual's particular case of drug abuse and other factors including co-occurring mental health problems. Alcohol and drug abuse rehabilitation programs in Denver can be performed on an outpatient basis or an inpatient basis, with inpatient alcohol and drug abuse rehabilitation programs providing substantially better success rates due to a higher quality of treatment program.
