I'm sure other readers have e-mailed you about this, but the the smell of marijuana can be wholly avoided by using a vaporizer.
They work by vaporizing the THC without actually burning the bud. The result is a smokeless high and an odor more reminiscent of potpourri than weed. The best vaporizers are still prohibitively expensive, but cheap (and portable) units can be had for under $200.00. It's a small price to pay to be rid of the unmistakable smell of marijuana.
