True, they were breaking the law, But that's not truly relevant if they harmed no one and if, as the case may be soon proven, the law was wrong to begin with. Thankfully there have always been individuals who "broke laws" to help society advance. There has been increasing support worldwide to end the "war on drugs" as many now feel that it has been an enormous waste of money and resources, including many in law enforcement. Sometimes it takes small individuals to bring about major change. Laws such as Segregation in the US or Apartheid in South Africa are now viewed as wrong and immoral and without individuals who broke those laws and helped bring about societal change, they would still be laws and people would still be suffering. I don't feel that anyone who broke the law by selling drugs was suffering but the assertion that "they broke the law" doesn't mean that these individuals who were perhaps brave enough to do so should be barred from contributing in a meaningful fashion today.
