laser cutting is dangerous as fuck depending on what you're cutting.

Yes. You want to read the MSDS section for burning of any material you're going to laser cut. Especially plastics.

Some are fine, some stinky, and some are death.

Fiberglass depends on the resin used, but you weren't getting through glass with 10W or 40W desktop laser.
Raw carbon fiber is actually fine from what I've heard, but coated stuff depends on exact epoxy/resin again.
