Now that a Sacramento jury has rendered a felony conviction in a criminal case that raised questions over reasonable personal use for medical pot, a major test stirs in San Diego over whether marijuana collectives are illegal sales operations. Undercover police officers with physicians' recommendations for medicinal weed targeted Donna Lambert, a 49-year-old cancer survivor who ran a marijuana network that provided home deliveries to medical users. Now Lambert, who operated "The Women's Health Cooperative," is due to go on trial April 13 on seven felony counts, including illegal sales of marijuana. She is a major focus of a legal push by the San Diego County district attorney's office.
