Yes, it is possible to quit cocaine cold turkey. However, quitting cold turkey can be very difficult and uncomfortable, and it may be safer and more effective to seek professional help and support from a healthcare provider, addiction specialist, or a drug rehabilitation program. Withdrawal symptoms from cocaine can include depression, anxiety, fatigue, insomnia, intense cravings, irritability, and physical symptoms such as muscle aches and tremors. A healthcare provider or addiction specialist can help you manage these symptoms and provide a safe and supportive environment for you to detox and recover from cocaine addiction.
