I am at a party, i have had two cans of soda. i used straws to drink them. however i have noticed alot of people appear to be on drugs. i'm worried they have snorted drugs and touched the straws. and i have ingested some. how likely? will i die?

It would be almost impossible for enough drug to be on a straw to cause any harm to the next straw user. The main health risk from this situation is for Covid-19, influenza, and common colds.

The chances you will get a significant amount of possible drugs in your system is minimal, a variety of other viral and bacterial infections remain possible specifically if sharing drinks or straws. Discussing with your friends your worries at a personal level will be best.

You will not die from this. You need to find a different set of friends who are not engaged in self-destructive behavior. For healthy diet: http://www.choosemyplate.gov/., exercise 30 minutes/day, drink enough water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs. Get HPV vaccine. Wish you good health!
