Yup.

An older friend who smoke and drank a ton switched to vapes, and methodically lowered the nicotine content every two-there weeks for months, then stopper nicotine and vaped the flavours but as there was no more nicotine, the habit wasn’t addicting and he just forgot about it more or less.

Now he’s been alone free for years, and reduced his drinking as well. Looks fucking healthy now.
