Primary care Primary care is the first part of residential rehab. In most cases its the only part you will need, but some people like to graduate to secondary care. Secondary care can only be an option after 12 weeks of primary care. Primary care can be anything from 4 to 12 weeks. A medical detox is normally between 7 to 14 days. In primary care you will invariably have a tailored medical detox depending on your substance misuse. Drugs like LSD, Powder Cocaine, Crack Cocaine and Cannabis do not need a medical detox. With these substances we offer medicine to restore your natural sleep pattern and get your appetite back on track. We do everything possible to make sure your detox and primary care are as comfortable as possible.
