Kelly Clarkson insists she isn't ''a pothead.''

The 33-year-old singer, who believes the US should legalise marijuana, claims she knows more people who have died from alcohol-related incidents and illnesses.

The 'Heartbeat Song' hitmaker said: ''I'm not even a pothead, I just think it's funny that we legalise something as destructive as alcohol or pills and not that. Don't get me wrong. I love me some alcohol, but I don't know anybody in rehab because of pot. And I know a ton of people that have died either from liver cancer or behind the wheel.

''We legalise things that are so disturbing for our bodies, but one that's completely fine, we say, 'No, that's bad for you.' I'm like, 'OK, enjoy your scotch. Enjoy your Xanax.' ''

Despite being very outspoken, Kelly would never consider getting involved in politics.

She told Rolling Stone magazine: ''Oh, my God, that's the worst job in the world. It's like being a football coach. When things are going well, the coach is just lucky, and then when everything goes to s**t, it's all the coach's fault.''

The blonde beauty is looking forward to experimenting more in the recording studio now that her six-album deal with RCA Records has come to an end.

She said: ''I haven't ever been able to pick who to work with as an artist, so it's nice now that it's a choice. It'll be cool to 'Breakaway,' for lack of a better term, and see what's out there. If I want to make a country record, I'll make a country record. If I want to make an R&B record, I'll make that. I've made enough money in my career. This is just the cherry on top.''
