but that has not gone &gt; as I hoped at all - the court was of the opinion that I had broken contact &gt; off with my daughter and therefore could not expect to get it back easily, &gt; even though they agreed it was in her best interests. Worse, a &gt; three-year-old police caution came up for cannabis possession. Again, I &gt; didn't consider this would be a big issue - I work with children as a &gt; Teaching Assistant and have been accepted onto a teacher training course &gt; as of September, I have passed all safeguarding criteria despite the &gt; caution. However, my ex has said she sees this as a reason not to allow me &gt; contact, she has described me as having a 'transient lifestyle', with &gt; 'sporadic' contact with my daughter, and described me as having a 'drink &gt; and drug' problem, none of which would stand up to close scrutiny. &gt; However, in the meantime, I am stuck not seeing my daughter. The position &gt; I'm in now is this - I volunteered to take a drug test to prove I am not a &gt; heavy drug user. I expected it to be a urine test, which I was confident I &gt; would pass. However, I've now found out it will have to be a hair test to &gt; stand up in court, which I am not confident I will pass because I am &gt; still, I admit, an occasional user of cannabis.
