Are cum carts safe?

So I ordered from from this vendor after hearing decent things and seeing their very decent prices for carts. My first order was for 2 carts(Skywalker OG and Sour Diesel) and they were fire. The disty was clear and kind of tasteless but I was baked. I wanted to sample some more so went back for a second order, this time ordering 4 carts(London Pound Cake,Cereal Milk,Grandaddy Purple,and Gushers. This time around I recieved only one clear cart, the rest were cum carts to put in mildly.

Now I'm not scared of a little cum so I went ahead and powered through to sample these cummy carts. Surprisingly they were mostly great, still no taste difference between them but they smack. That is until I got to the Grandaddy Purple. This cart not only had cum in it but also floating debris(See pic). For science I hit this bitch once and starting coughing so hard I almost puked, wife took this as a good thing and hit it herself and same thing. We both could not breathe right the rest of the night.

I emailed the vendor and was told the debris was waxes that made it through the distillation procces and that it was safe to hit. They also said they would throw in some freebies with my next order but now I'm not sure about this place to be honest. I'm not well studied on distillate but is this really safe to hit? Am I making a big deal over nothing?
