Can you test positive for thc if all you do is handle marijuana. such as rolling a joint, growing and cutting it up?

Doubt it ...but: I doubt that it would show at all with this type of contact. However, I believe there are home urine tests you can find in various locations in stores or online that are not expensive. You can look into the reliability of such products and test at home if this is important. A first morning urine is more concentrated & more likely to show any.
