Project TE-5001 was a Liggett & Myers project circa 1971-1977 to develop a low tar, low nicotine cigarette with an increased smoke pH that would have more freebase nicotine in its smoke, and thus give the smokers a higher nicotine "impact." [1][2]

A report created near the beginning of the project stated,

Increasing the pH of a medium in which nicotine is delivered increases the physiological effect of the nicotine by increasing the ratio of free base to acid salt form, the free base form being more readily transported across physiological membranes. We are pursuing this project with the eventual goal of lowering the total nicotine present in smoke while increasing the physiological effect of the nicotine which is present, so that no physiological effect is lost on nicotine reduction.[3][4]
