Hi there, thanks for asking. As you mentioned cocaine and speed can be harmful for the brain function which is much more probable in chronic use. They can cause mood swing
(moods of highs and lows) and also can lead to impulsive behaviors (like gambling and aggressiveness). They could also cause vascular problems and might even lead to heart damage. They are good non-pharmacological methods for cocaine and speed (methamphetamine
) abstinence (like method of matrix) which you can ask your doctor to refer you. You can easily prevent your mood from highs and lows and I am happy that you are aware of that. I wish you the best health.
