Amazon Prime is laced with crack...?

I've heard rumors that Mickey D's laces their fries with nicotine or crack to get people addicted to them.  I wonder if Amazon does the same thing with their Prime service.  During my 30-day trial, I've ordered about 18 things.  There is something addictive about being able to order a book for $3.92 with free 2-day shipping and no tax.
