Dax Shepard wants his wife Kristen Bell to throw an ecstasy party. 

The 43-year-old actor - who developed a substance abuse problem at the age of 18 - recently celebrated 14 years of sobriety but, although it took him a long time to curb his habits back in the day, he is trying to encourage his spouse to dabble in drugs. 

Speaking on the podcast WTF With Marc Maron, the Frozen star said her husband believes "you shouldn't leave earth without having tried mushrooms or ecstasy." 

And, despite his past, he understands that "he lost his privilege with them [drugs] because he can't handle it; his brain doesn't have the chemistry to handle it." 

But that doesn't mean the Employee Of The Month star won't be in attendance when his wife does throw a drugs fest but, rather than get involved, he'll be a "sober coach" to make sure everyone has a safe and comfortable time at the party. 

Dax is no stranger to avoiding temptation as Kristen has admitted she smokes marijuana around him at least once a week and he doesn't seem to mind. 

The blonde beauty - who has two daughters Lincoln, five, and Delta, three, with Dax - explained: "I smoke around my husband and it doesn't seem to bother him." 

When asked how many times she lights up, she replied: "Once a week, if I am exhausted and we are about to sit down and watch 60 Minutes, why not?"
