It worries me that people think that reporting ex for dope = evidence. Or that actual evidence of drug use automatically = no contact/supervised contact..
In my case, ex admitted to smoking dope in order to avoid being tested for it. The judge ruled that the cost of testing wasn't justified, as he wasn't disputing it. He was told not to smoke during his contact with our DS, aged 2. So he said ok, and that was that! Even when he tested positive for cocaine (crack)prescription meds(not his prescription) and chroni? excessive alcohol use, the social worker
Aaargh, my phone is being a dick!)
Anyway, the social worker's report recommended unsupervised contact, leading to overnight stays! I was ordered to make him available for contact all this time but couldn't even get supported contact, never mind supervised!
Can you afford a solicitor/court case, OP? Can your ex? If not, it might not even get to court. As a PP said, dope smokers tend not to be highly motivated individuals.
If you really believe your baby is being exposed tonabis, or indeed, any smoke and to customers in and out, then you can reasonably stop the contact.
The dogs alone would be enough for me, tbh.
The onus would then be on him to take action. It doesn't sound like he can afford legal representation, nor that he is mature enough to put himself across well in court.
