5 mg/325 mg (oxycodone/acetaminophen) dosage question (kinda urgent)

Hey guys, i tried oxy about a week ago and didnt really feel it, i look 15 mg orally (just swallowed the pills) and it was really underwhelming. thinking of snorting one tonight and taking 4 more orally, is this safe? ik its a big jump from 15 mg but im very experienced with other substances like shrooms, weed, lsd, ketamine, and benzos. just wanna make sure im not gonna need my stomach pumped XD. thanks in advance
