Smoking
After smoking for seventeen years I gave up. I was prescribed patches and then gum courtesy of the NHS. I was no longer addicted to al the shit you get from smoking tobacco. After three years I am still on nicotine lozenges. No one knows what damage nicotine alone does to your body.
1mg, 2mg, and 4mg lozenges all cost the same. There is no law against buying the strongest and cutting the tablets in half.
Vapes are good and cheaper than cigarettes too. Trendy young dude suck on vapes. It is very difficult to monitor your consumption which is why I don’t vape. OK I only vape on special occasions.
