Most of the products like “Legal Bud” contain no THC and won't get you high. It has the
same looks, same smell, same taste, but there’s no high.
On the other hand, there are very few websites that do sell real marijuana online. A few
have advertised in High Times and CC magazines. They sell at extremely high prices and
won't usually sell more than an ounce. One website sold real marijuana but it was about
$500 an ounce. They also make you get a "secure" email address.
Years ago the assumption was that it was completely safe to purchase small amounts
because the belief was that LEOs had neither had the resources or the desire to go after
small-timers. This wasn't true. Homes were raided with warrants issued for "suspicious
mail volume."
