Biden recently stated he was going after nicotine.

The “Party of science” apparently determined to wring more $$$$ out of “health care” https://www.tampabay.com/news/health/study-finds-nicotine-safe-helps-in-alzheimers-parkinsons/2175396/

For starters, nicotine by itself isn't very addictive at all, according to Dr. Paul Newhouse, the director of Vanderbilt University's Center for Cognitive Medicine. Nicotine seems to require assistance from other substances found in tobacco to get people hooked.

I suspect Big Pharma targeting another (cheaper) option to address the medical conditions addressed in the article.

What makes nicotine especially attractive as a treatment is the fact it causes virtually no side effects, according to Newhouse.

"It seems very safe even in nonsmokers," he said. "In our studies we find it actually reduces blood pressure chronically. And there were no addiction or withdrawal problems, and nobody started smoking cigarettes. The risk of addiction to nicotine alone is virtually nil."

No side-effects means no additional, compensatory medications (ie no additional $) So, Big Pharma versus Big Tobacco. My money is on Pharma to win this.
