17. Can I grow or use medical marijuana with children in the house?
There is nothing in state law against this. However it's advised to keep your medical marijuana away from children. Make sure that you don't leave edibles around where kids can get them, and keep gardens away from where they play.
In rare cases Child Protective Services has become involved, mostly in cases with large plant numbers, evidence of sales, neglect, or messy divorce proceedings. In such cases, CPS tends not to be understanding about medical marijuana and can always allege child endangerment.
