Willie Nelson definitely has no plans to take this job and shove it when it comes to the cannabis company he owns. "[I'm] chief tester," the 85-year-old country icon told Jimmy Fallon on Tuesday's Tonight Show about his duties at work. "I haven't run across any [marijuana] that I didn't like." Fallon also pointed out that Nelson graces the cover of Rolling Stone's new weed-themed issue--in which Willie claims that pot saved his life. "I used to smoke two, three packs of cigarettes a day, drink whatever there was to drink," Nelson explained. "I threw out the cigarettes, rolled up 20 joints and I haven't smoked a cigarette since."
