Pan masala is of two types:
Plain pan masala (blue packet Pan Parag)
pan masala with nicotine
which comes as white packet Pan Parag (zarda or gutkha).
Both are addictive. The white packet is more addictive than the other because of nicotine content. The plain pan masala contains arecanut which is also addictive.
You may try nicotine chewing gums if your pan masala contain nicotine, otherwise for plain pan masala you may have to quit by yourself and seek the help of a psychiatrist
who may give you medications for any specific symptoms if you have.
