E-wallet services, such as Venmo or Paypal, also shy away from working with the marijuana industry. Berke said they dont want to deal with the potential bad press, or the risk of acquiring dirty money. He said PayQwick ensures its clients pay taxes, comply with rules and regulations, and it bars users from transferring funds outside their own state to avoid potentially breaking the law. Chris Cogdill, who represented Tamisium Extractors at the expo, said hes optimistic because of the industrys quickly growing sophistication. Cogdill said he once spent time in jail for eight grams of marijuana. Now he works for a company that developed an extraction method and recipes for wax and oil manufacturers. I cant wait to see where this all goes, Cogdill said. Arizona voters in 2010 passed the Arizona Medical Marijuana Act, which allows people with certain medical conditions to use medical marijuana after obtaining a doctors recommendation. Voters in November rejected a measure to legalize recreational marijuana in the state, but Safer Arizona has filed to put recreational marijuana back on the ballot this year, potentially opening Arizona up to even more canna-business.
