Editor's note: The following are questions received from viewers of "Mad Money," seen every day at 6 p.m. EDT on CNBC.

My son is 2 years old, and I'm thinking of putting some money aside for his education. What stocks in the pharmaceutical business have the best long-term outlook?-- Norm from Canada

James J. Cramer:

The drugs are not my favorite niche in health care, for either the short or long term. That said, I believe that

GlaxoSmithKline

(GSK) - Get Report

and

Schering-Plough

(SGP)

have the best outlook, based on their product portfolio and patent protection.

What is your take on Sirius Satellite Radio (SIRI) - Get Report?-- Tom from Tennessee

James J. Cramer:

The best I can say is that I'd hold on to it if I already owned it. Mel Karmazin is a great manager, but this company has already spent a lot of money and set many lofty near-term goals. In my opinion, Sirius must deliver several good quarters in order to get the stock up into the high single-digits.

What are your favorite natural gas stocks to hold for the next few quarters?-- Ed from Pennsylvania

James J. Cramer:

One company I own for my charitable trust,

ActionAlertsPLUS,

EnCana

(ECA) - Get Report

, has the best near-term growth prospects in my space. That said, I also like

Chesapeake Energy

(CHK) - Get Report

, which has a solid management team and its own portfolio of attractive natural gas assets.

How does one talk to Jim?-- Barbara from South Carolina

James J. Cramer:

The best way to ask me a question on the air at "Mad Money" is to call 1-800-743-CNBC (2622).
