LSA: Drug Testing and Extraction

I recently came into some LSA containing Hawaiian Baby Woodrose seeds. Unfortunately I'm on probation for marijuana possession, but have not had a drug test yet so I don't know what type of test they will use. If they tested for LSD I imagine there would be a false positive, but what do you guys think the chances of that are? Do you know how long LSA will stay in my system?

Also I was wondering what your guys favorite methods of extraction are. I've read some with ginger, some with cinnamon (supposed to produce LSH, but I'm not sure how true those claims are), and some with lemon.
