need nitrous again

Trying to find a place close to Bel Air MD that refills nitrous. Maryland Performance does not do it anymore. The last time I posted this question on here someone told me about American Auto Repair in Joppatown. Well, they're out of nitrous and they're going on vacation and the last couple times I've gone there they either don't have it or they're not at the shop during "shop hours".

So...does anyone know where I can get my nitrous refilled??

Thanks
 
Dentists won't sell nitrous. Nitrous oxide for cars and nitrous oxide for clinical use are very different. The car's version has about 100 ppm of sulfur..so you get sick if you try to huff it. A dentist has no excuse to sell medical-grade nitrous oxide. They have very little to gain..it's a huge liability.
 
try places that distribute shielding gases for welding, some distribute medical gases too so you could get nitrous, I just don't know if there are any special restrictions, but it is worth a shot.
