Tips for Parents & Educators • Get the facts, know the risks. • Start the conversation. • Be patient, ready to listen and supportive • Keep the conversation going. • Set a positive example.
Public health response • Inform youth, teachers, and parents about risks. • Presentations to youth, parents, teachers (nearly 100 since 01/19) • Materials are being developed in partnership with BC Lung • Training of VCH staff • Regulations now in place to prohibit sales to minors. Use in public spaces has to be consistent with smoking bylaws. • Attention needs to be devoted to restricting product promotion, preventing sales to minors. • Advocacy continues to make vaping less appealing by restricting flavours, limit access to adult only shops.
