View Full Version : Switching from Cannabis to Concerta.

I have ADHD and was prescribed Concerta.

However, I smoke cannabis, extremely heavily. Most of the day, every day for 4 years.

I will be quitting the cannabis and starting the Concerta. However, whenever I stop smoking, I experience withdrawal symptoms like insomnia, loss of appetite and some nausea.

Must I wait for my body to go for the 1~ week long withdrawal process before beginning the Concerta?

Or does it not matter and I can I just immediately quit the weed and begin taking the Concerta as prescribed and my body will just eventually adjust to it?
