Los Angeles, Feb 4 (IANS): Singer Demi Lovato urges people to treat drug addiction seriously and wants them to take action against it.

The "The X Factor" judge, who has struggled with marijuana and cocaine addiction in the past, took to Twitter to hit out at celebrities who "glamourise" drug addiction, reports contactmusic.com.

"I wish more people would lose the stigma and treat addiction as the deadly and serious disease that it is. Drugs are not something to glamourise in pop music or film to portray as harmless recreational fun. It's not cute, cool or admirable," she posted on the microblogging site recently.

"It's time people start really taking action on changing what we're actually singing or rapping about these days, because you never know if you could be glamourising a certain drug to a first time user or alcoholic who could possibly end up dead because they end up suffering from the same deadly disease so many have already died from. This stuff is not something to mess with."

This comes after the recent death of actor Philip Seymour Hoffman, which is said to be due to drug abuse.
