ALASTAIR Clarkson's sabbatical has taken an interesting twist, with the AFL coaching great joining a sports science company that researches medicinal cannabis for treatment.

Clarkson, Australian basketball legend Lauren Jackson and top jockey Damien Oliver have been announced on an advisory board for Melbourne company Levin Health.

The connections are obvious, with former AFL coaches association boss Mark Brayshaw the company's managing director.

Brayshaw's brother and high-profile sports commentator James is the company sports and media advisor.

Clarkson, who coached Hawthorn to four premierships, is taking a year off and went to the United States last month for study and business.

"Regardless of whether it's amateur or professional, AFL can be a brutal contact sport," Clarkson said in a company statement.
