Drug withdrawal can be dangerous if done without expert guidance. This is due to the severity of the withdrawal symptoms and the likelihood of overdosing after a relapse. If you’ve managed to go for a few days without a drug, your body has already started to lower its tolerance, so in the unfortunate event you relapse, your body may not be able to handle the intake, and overdose can occur. This is why seeking medical advice and ensuring you have appropriate care around you is vital for undergoing a drug detox.
