Everybody I've seen who quits cigarettes gets discolored phlegm and the respiratory tract begins healing. Everyone also gets changes in taste of some sort as the taste buds heal up. Marijuana is not as associated with damage to the respiratory tract and in theory quitting cigarettes but still smoking marijuana would still allow at leaast some healing to occur.

There seems to be a second question about quitting marijuana but not any specific information about that more complex question. A direct question would get direct answers.

Dear
Welcome to HCM
We understand your concerns

I went through your details. If you’re ready to stop smoking marijuana and willing to get the support you need, you can recover from addiction and abuse —no matter how bad the addiction or how powerless you feel. The first step in treating addiction is accepting that you have a problem. Confronting an addiction and accepting responsibility for your actions isn’t easy. But it’s a necessary step on the road to treatment and recovery. You should then consult a psychiatrist / psychologist who fill follow this treatment. 1. Detoxification using medicines. 2. Behavior modification with the help of therapies. 3. Counseling. 4. Medication to sustain and 5. Long term support. These given steps are essential for any addict to get effectively rid of addiction. Therefore, you need to stick to the treatment plan and cooperate with your psychiatrist / psychologist. Mind power building therapy, motivation therapy etc should help you doing so. I suggest you to consult a psychologist or de addiction therapist.
