Patient's Query

Hi doctor,

Five nights ago, I was out with my friend, and he convinced me to try a marijuana tincture that he said was about 65-75% ethanol. First, I tried 0.1 ml under the right side of my tongue. I held my head back and essentially let it sit there for 20-30 seconds. I felt a burn from the ethanol, but my friend said to expect that, and it was nothing unbearable. Later that night, I tried 0.15 ml more under the left side of my tongue. Again, I held my head back and let it sit for 20-30 seconds, and again I felt a burn from the ethanol. Please note that these doses are each equivalent to about two drops. Over the next three to four days, I had a canker sore under my tongue, but it went away within three to four days. However, I have had a dry mouth since that night of trying the tincture, to the extent that I have been unable to sleep for more than four to five hours at a time because I wake up with a very dry mouth. It seems to have gotten a bit better over the last five days, but not much. I have just been drinking a lot of water (10-12 bottles per day), and I am worried. Please note that I have not taken any marijuana nor any other kind of drug nor medication since that night. I have been completely sober over the last five days while experiencing the dry mouth (and also before the tincture). Since I am not a doctor, I do not know what to look for when I lift my tongue, and I figured that since the residual canker sore pain went away within a few days, it was not a big deal. My question is, why am I experiencing dry mouth, and is it something that I can expect to go away or resolve on its own soon?


Welcome to icliniq.com.

Marijuana contains tetrahydrocannabinol or THC and its active form is known for its psychotropic effects. In addition, it also does produce dryness due to its anticholinergic effect on the system. This is the reason why you tend to have a dry mouth and often feel thirsty. The anticholinergic effects do last for a considerable amount of time even though its psychotropic effects get neutralized in few hours time. There is nothing that you need to worry about, as this will resolve on its own in a few days time. Keep drinking warm water every 2 hours. Make sure you avoid using any recreational drug in the future.
