Both Silberman and Sutton cited Scalias opinion in 2005 upholding strict federal regulation of marijuana in the case of Angel Raich, a Californian who used home-grown marijuana to relieve her pain. If Congress could regulate Angel Raich when she grew marijuana on her property for self-consumption, Sutton wrote, it is difficult to say Congress may not regulate the 50 million Americans who self-finance their medical care.

Yes, which is why Scalia will be a toss up during the Patient Protection and Affordable Care Act arguments. I would not be surprised if Scalia favors the regulatory expansion of "Obamacare".
To understand why Scalia is “comforting” in expanding the Commerce Clause, research his past employment.
