Sample Conversation

Here’s a sample conversation a user might have with Bella, about Nicotine Replacement Therapy (NRT).

User: “Alexa, Open Bella.”

Bella: “Hello, it's Bella, your personal stop-smoking coach. Here is something to remember for when you do feel that temptation coming. Fact: smelling better is just one benefit of quitting smoking. Have the best smoke-free day ever!”

User: “What is NRT?”

Bella: “NRT works by releasing controlled amounts of nicotine into the body without the tar, carbon monoxide, and poisonous chemicals you get from tobacco. It's these chemicals that are the most harmful, not nicotine. All types of NRT deliver a lower does of nicotine than you would get from cigarettes and are much safer.”

User: “What are the types of NRT?”

Bella: “NRT is available in a variety of forms: gum, patch, inhaler, microtab, lozenge, and nasal spray. They are all as effective as each other so the choice is a personal and practical one. This range is big enough to allow you to use a type that will suit your lifestyle.”

User: “How do I use a lozenge?”

Bella: “An NRT lozenge is like a sweet that you suck slowly. It gives you NRT in a controlled way.”

User: “Is NRT dangerous for your health?”

Bella: “No, the damage to the health of the smoker is caused by the tar, carbon monoxide, and chemical compounds found in cigarette smoke. NRT products help smokers reduce their nicotine cravings and withdrawal symptoms without inhaling these harmful elements. NRT is safer than most people realize.”

User: “Where can I get NRT?

Bella: “NRT is sold in shops and supermarkets and over the pharmacy counter. If you don't get it on prescription make sure you read the instructions on the package and speak to your doctor or pharmacist if you're not sure of anything.”

User: “Is cutting down a good idea?”

Bella: “There is no evidence that merely cutting down as a strategy makes a quitting attempt more likely to succeed. The only way to really reduce the risks from smoking is to stop completely. If you can not stop smoking totally, an option is to use NRT while cutting down.”

User: “Some motivation?”

Bella: “That craving is temporary. It's not you. Recognize when you have a craving and watch it go away.”

Users just have to say “stop” to end the conversation.
