Hi there ~
I understand your concerns. The white blisters on the tip of your tongue, cold
sores on your lips and white patches on your jaw line after smoking meth
are all related and the remedy is to stop smoking meth. This would instantly cure your problems with your skin. I believe that you also need to keep the areas clean and dry and use medications and consult a dermatologist
if they do not subside despite your best efforts. I also believe that yoyo may need to seek the expert help of a psychiatrist
for your meth dependence as soon as possible.
I hope this helps. Take care and have a lovely day!
