Workit clinicians are non-judgmental and operate according to principles of harm reduction—they will not refuse treatment due to substance use. For other doctors, both medical ethics and recommendations from The American Society of Addiction Medicine say that your doctors should not deny you care due to active alcohol and/or drug use. If possible, it is recommended that you not drink or use drugs if you have hepatitis C (to protect your liver). But you should receive treatment no matter what.
