The effects of nicotine and lobeline are quite similar, with psychoactive effects at small dosages and with unpleasant effects including vomiting, muscle paralysis, and trembling at higher dosages. For this reason, "H. longiflora" is often referenced for both its toxicity and its ethnobotanical uses.When uprooting this weed, it is important to wear gloves: the sap is an irritant which can be absorbed through the skin, and a small amount of sap in the eyes can cause blindness.
