Neither snow, nor sleet, nor weed...

This story is somewhat confusing:

An Amarillo woman who mailed 78 pounds of marijuana to herself was sentenced to 2 1/2 years in federal prison Monday.

Tiffany Joy Kelly, 28, pleaded guilty in October to one count of illegal use of a communication facility, the U.S. Attorney's Office in Dallas said in a news release. She has been in custody since her arrest in July, after a postal inspector in El Paso became suspicious of two Express Mail parcels.

[...]

Prosecutors said she admitted buying the marijuana and mailing it to herself so she could distribute it.

Why didn't she just hold on to the weed? I can't figure out why she felt the need to mail it to herself. Maybe she was high at the time.
