Did you know that some dealers put embalming fluid in marijuana? Yea, embalming fluid.

And that's where you would be getting your marijuana from - a dealer. Who know who all was killed or harmed trying to get this drug to you.

In terms of anxiety, I think marijuana does more harm than good. Yea, there is a temporary relief, but this can be replaced with profound paranoia and freaking out.

If your dad is a cop, then he knows the signs of marijuana use probably way more than the average parent. My guess is that this would be very very hard to hide from him anyway.

If relief is what you are seeking there are other, healthier ways to go about it. You're obviously smart, and prepping yourself for long term success and productivity. I would try to opt for one of these long term, healthy ways to help yourself.
