The Cheech & Chong star is set to front a talk show called Almost Legal which will be broadcast on YouTube.com, and he will address issues such as his ongoing battle with rectal cancer.

He says of the new project, "It's a stoner's version of Jon Stewart... (I will discuss) anything that affects the pot smoker's status in any way, negative or positive."

In a post on Twitter.com, he adds, "I am going to be hosting my first talk show man!!! Almost Legal with Tommy Chong. Coming soon."

The show is set to debut in the autumn (15) and will feature interviews with stars including actor Danny Trejo.
