i've used addy to both come down and twice recreationally simutaniously with cocaine, this was on day 5 of smoking coke without sleep, i made it to day 9 and those 4 days are abit of a blur but they seemed to just fly by but this is a particularly dangerous combination i must implore and thats coming from someone who uses the two substances basically regularly, i get by fine if i really want to go ahead with the combo because i'm on high dose opiates which lower my heart rate and allow me to use more stimulants than i otherwise would but its a tricky combo, i remember i only took about 90mg for my initial dose and didn't take anymore till a good 20 hours later, and then repeat same again but i think if anything, addy or amps in general should only be used to attempt to smoothen out a coke comedown (my comedowns are rather smoothe because i smoke my coke so 20-40 minutes and half of its already out of my system if not more vs snorting lasts much longer, but i wouldn't rule out putting 10mg into a solid line of coke would be quite a nice boost if you don't mind altering the coke high (i used to drink rediculously when id smoke up but i don't anymore because i now genuinely feel if you want to fully atleast for smoking it, enoy the cocaine you should take it alone or with an opiate, I'm not a believer in the huge danger warnings with speedballs because everytime i smoke up whether i like it or not, i'm technically speedbaling, but what i can say about speedballing is that you want to try not to be up and down too close to eachother because i speculate thats when you can confuse the body and weird shit happens but the practice is generally safe if you respect your drugs
Forsure won't give you cancer but i want to warn you about the addy, and ive said it on multiple threads, it may look like a fine powder, i know when i crush it in my mortar and pestle it certainly does however! it's actually like tiny shards that almost resemble glass so keep this in mind when snorting crushed adderall, atleast the XR form of it, i think the pills that are essentially all powder are good to go but there's a hell of alot of filler in them compared to the XR form, please attempt putting the addy under your tongue then let it dissolve over about 3-5min before you swallow whatevers left to me it tastes somewhat bitter sweet so i really don't mind it at all, it hits like snorting and lasts 3x longer and saves your nose
i'm gonna refer to the actors of Wolf of Wallstreet with leonardo di caprio, i believe whats his name, jonah hill snorted so much fake cocaine filming the movie that he was hospitalized because his lungs became so congested with the powder mix they were using on-set
so there can be some potential harm, but as long as you're not sucking whatever you snort back as hard as you possibly can you should be alright because you should get a drip at some point (your nose, mouth and ears are all connected) and you'll get a drip of what you snorted, which'll have a certain % of x substance in it aswell, i used to love the coke drip before i started smoking just thinking of that sweet numbing and then a chemically bitter lightning kind of zap to my tastebuds from the back of my throat, i can't believe i'm thinking of going for a bag and railing right now but i don't think thats the best course right now since i've been awake for 3-4 days *i lost count around the 30 hour mark*
also if you plan on going for a coke and addy combo, you genuinely might aswell go for some meth because it feels as good as coke and has all the benefits of amphetamine, i really want some meth right now
